Chapter 1 – Universal Socket Connectivity Design Considerations Good engineering practices must be adhered to when designing a printed circuit board (PCB) containing the SocketModem module. Suppression of noise is essential to the proper operation and performance of the modem itself and for surrounding equipment. Two aspects of noise in an OEM board design containing the SocketModem must be considered: on-board/off-board generated noise that can affect digital signal processing.
Chapter 1 – Universal Socket Connectivity Electromagnetic Interference (EMI) Considerations The following guidelines are offered to specifically help minimize EMI generation. Some of these guidelines are the same as, or similar to, the general guidelines but are mentioned again to reinforce their importance. In order to minimize the contribution of the SocketModem-based design to EMI, the designer must understand the major sources of EMI and how to reduce them to acceptable levels. 1.

Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) SocketModem Parallel Interface The modem supports a 16550A interface in parallel interface versions. The 16550A interface can operate in FIFO mode or non-FIFO mode. Non-FIFO mode is the same as the 16450-interface operation. FIFO mode’s unique operations are described in this chapter.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) Register Functional Definitions The following table delineates the assigned bit functions for the twelve internal registers. The assigned bit functions are more fully defined in the following paragraphs. Internal Registers Register No. 7 6 5 4 3 2 2 1 (DLAB = 0) 0 (DLAB = 0) 0 (DLAB = 0) 1 (DLAB = 1) 0 (DLAB = 1) Register Name Scratch Register (SCR) Modem Status Register (MSR) 7 6 5 BIT No.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) IER – Interrupt Enable Register (Addr = 1, DLAB = 0) The IER enables five types of interrupts that can separately assert the HINT output signal (See the Interrupt Sources and Reset Control table in the IIR section of this chapter). A selected interrupt can be enabled by setting the corresponding enable bit to a 1, or disabled by setting the corresponding enable bit to a 0.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) FCR – FIFO Control Register (Addr = 2, Write Only) The FCR is a write-only register used to enable FIFO mode, clear the RX FIFO and TX FIFO, enable DMA mode, and set the RX FIFO trigger level. Bits 7-6 RX FIFO Trigger Level FCR7 and FCR6 set the trigger level for the RX FIFO (Receiver Data Available) interrupt.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) IIR – Interrupt Identifier Register (Addr = 2) The Interrupt Identifier Register (IIR) identifies the existence and type of up to five prioritized pending interrupts. Four priority levels are set to assist interrupt processing in the host. The four levels, in order of decreasing priority, are Highest: Receiver Line Status, 2: Receiver Data Available or Receiver Character Timeout. 3: TX Buffer Empty, and 4: Modem Status.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) LCR – Line Control Register (Addr = 3) The Line Control Register (LCR) specifies the format of the asynchronous data communications exchange. Bit 7 Divisor Latch Access Bit (DLAB) This bit must be set to a 1 to access the Divisor Latch Registers during a read or write operation. It must be reset to a 0 to access the Receiver Buffer, the Transmitter Buffer, or the Interrupt Enable Register.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) MCR – Modem Control Register (Addr = 4) The Modem Control Register (MCR) controls the interface with modem or data set. Bit 7-5 Not used Always 0 Bit 4 Local Loopback When this bit is set to a 1, the diagnostic mode is selected and the following occurs: 1. Data written to the Transmit Buffer is looped back to the Receiver Buffer. 2.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) LSR – Line Status Register (Addr = 5) This 8-bit register provides status information to the host concerning data transfer Bit 7 RX FIFO Error In the 16450 mode, this bit is not used and is always 0. In the FIFO mode, this bit is set if there are one or more characters in the RX FIFO with parity error, framing error, or break indication detected. This bit is reset to a 0 when the host reads the LSR and note of the above conditions exist in the RX FIFO.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) MSR – Modem Status Register (Addr = 6) The Modem Status Register (MSR) reports current state and change information of the modem. Bits 4-7 supply current state and bits 0-3 supply change information. The change bits are set to a 1 whenever a control input form the modem changes state from the last MSR read by the host. Bits 0-3 are reset to 0 when the host reads the MSR or upon reset.
Chapter 2 – SocketModem (MT5600SMI & MT5656SMI) SCR – Scratch Register (Addr = 7) The Scratchpad Register is a read-write register at location 7. This register is not used by the modem and can be used by the host for temporary storage. Divisor Registers (Addr = 0 and 1, DLAB = 1) The Divisor Latch LS (least significant byte) and Divisor Latch MS (most significant byte) are two read-write registers at locations 0 and 1 when DLAB = 1, respectively.

Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92) SocketModem Parallel Interface Internal Registers The SocketModem parallel interface is a mimic of a 16C550A UART. It is similar to the MIMIC interface used in the Zilog Z80189. The SocketModem mimic (MMM) takes advantage of this standard interface while replacing the serial to parallel data transfer with a less complicated parallel to parallel data transfer. The MMM interface controls an 8-bit parallel data transfer which is typically interrupt driven.
Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92) A typical (interrupt driven) write to the RX block is a two-step process. The MMM micro-controller must first write the 3 error bits to a shadow MMM LSR status register. Next, the micro-controller writes the data to the RX FIFO and during this write operation, the 3 error bits are directly loaded from the LSR shadow register into the bits 810 of the selected (11 bit-wide) FIFO register.
Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92) Time Out Interrupts The interrupts are enabled by IER bits 0-3. Care must be taken when handling these interrupts. Following a reset the transmitter interrupt is enabled, the SocketModem will issue an interrupt to indicate that transmit holding register is empty. This interrupt must be serviced prior to continuing operations. The LSR register provides the current singular highest priority interrupt only.
Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92) RBR – Receive Buffer (RX FIFO) All eight bits are used for receive channel data (host read/data in; host write/data out). The three error bits per byte are copied into bits 2, 3, and 4 of the LSR during each host I/O read; therefore, they are available for monitoring on a per-byte basis. THR – Transmit Holding Register (TX FIFO) All eight bits are used for transmit channel data (host write/data out; host read/data in).
Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92) FCR – FIFO Control Bits 6–7: Bit 5: Bit 4: Bit 3: Used to determine RX FIFO trigger levels. Used to detect a change in the FCR. TX FIFO overrun bit. DMA mode select. If bit 3 is a 0, the 16450 mode is enabled which does only single-byte transfers. When bit 3 is a 1, it enables a multiple byte (FIFO mode) data transfer. Bit 2: TX FIFO reset. This will cause TX FIFO pointer logic to be reset (any data in TX FIFO will be lost).
Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92) LSR – Line Status Bit 7: Error in RX FIFO. This bit is always set to 1 if at least one data byte in the RX FIFO has an error. This will clear when there are no more errors in the RX FIFO. Bit 6: Transmitter empty. This bit is the same as LSR bit 5 (THRE) in MMM Bit 5: Transmitter holding register empty.
Chapter 3 – SocketModem (MT5634SMI-34 & MT5634SMI-92) SCR – Scratch The host programmer uses this register for temporary data storage. DLL – Divisor Latch (LSByte) This register contains low-order byte for the 16-bit clock divider. It is kept to maintain register set compatibility with the 16C550A interface. However, it is not used for clock generation since MMM does not require the generation of a real baud clock.
