AR-B1551 User’s Guide 2.3 KEYBOARD CONTROLLER The 8042 processor is programmed to support the keyboard serial interface. The keyboard controller receives serial data from the keyboard, checks its parity, translates scan codes, and presents it to the system as a byte data in its output buffer. The controller can interrupt the system when data is placed in its output buffer, or wait for the system to poll its status register to determine when data is available.

AR-B1551 User’s Guide 2.4.2 Real-Time Clock and Non-Volatile RAM The AR-B1551 contains a real-time clock compartment that maintains the date and time in addition to storing configuration information about the computer system. It contains 14 bytes of clock and control registers and 114 bytes of general purpose RAM. Because of the use of CMOS technology, it consumes very little power and can be maintained for long periods of time using an internal Lithium battery.
AR-B1551 User’s Guide 2.5 SERIAL PORT The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are used to convert parallel data to a serial format on the transmit side and convert serial data to parallel on the receiver side. The serial format, in order of transmission and reception, is a start bit, followed by five to eight data bits, a parity bit (if programmed) and one, 1.5 (in a five-bit format only) or two stop bits(in a 6,7, or 8-bit format).

AR-B1551 User’s Guide Bit 7: This signal may become active during data entry, when the printer is off-line during printing, or when the print head is changing position or in an error state. When Bit 7 is active, the printer is busy and cannot accept data. Bit 6: This bit represents the current state of the printer’s ACK signal. A0 means the printer has received the character and is ready to accept another.
