Section 1 Connecting the Emulator with the User System 1.1 Components of the Emulator The E10A-USB emulator supports the SH7619. Table 1.1 lists the components of the emulator. Table 1.1 Components of the Emulator Classification Component Hardware Appearance Quantity Emulator box 1 User system interface cable USB cable 1 1 Remarks HS0005KCU01H: Depth: 65.0 mm, Width: 97.0 mm, Height: 20.0 mm, Mass: 72.9 g or HS0005KCU02H: Depth: 65.0 mm, Width: 97.0 mm, Height: 20.0 mm, Mass: 73.
1.2 Connecting the E10A-USB Emulator with the User System To connect the E10A-USB emulator (hereinafter referred to as the emulator), the H-UDI port connector must be installed on the user system to connect the user system interface cable. When designing the user system, refer to the recommended circuit between the H-UDI port connector and the MCU. In addition, read the E10A-USB emulator user's manual and hardware manual for the related device. Table 1.

1.5 Recommended Circuit between the H-UDI Port Connector and the MPU 1.5.1 Recommended Circuit Figure 1.2 shows a recommended circuit for connection between the H-UDI port connector (14 pins) and the MPU when the emulator is in use. Notes: 1. Do not connect anything to the N.C. pins of the H-UDI port connector. 4 2. The /ASEMODE pin must be 0 when the emulator is connected and 1 when the emulator is not connected, respectively.
When the circuit is connected as shown in figure 1.2, the switches of the emulator are set as SW2 = 1 and SW3 = 1. For details, refer to section 3.8, Setting the DIP Switches, in the Debugger Part TM of the SuperH Family E10A-USB Emulator User’s Manual.

Section 2 Specifications of the Software when Using the SH7619 2.1 Differences between the SH7619 and the Emulator 1. When the emulator system is initiated, it initializes the general registers and part of the control registers as shown in table 2.1. The initial values of the actual SH7619 registers are undefined. When the emulator is initiated from the workspace, a value to be entered is saved in a session. Table 2.
5. Memory Access during User Program Execution When a memory is accessed from the memory window, etc. during user program execution, the user program is resumed after it has stopped in the emulator to access the memory. Therefore, realtime emulation cannot be performed.
Table 2.2 Watchdog Timer Register Register Name Usage Register WTCSR(W) Write Watchdog timer control/status register WTCNT(W) Write Watchdog timer counter WTCSR(R) Read Watchdog timer control/status register WTCNT(R) Read Watchdog timer counter • The watchdog timer operates only when the user program is executed. Do not change the value of the frequency change register in the [IO] window or [Memory] window. • The internal I/O registers can be accessed from the [IO] window.
2.2 Specific Functions for the Emulator when Using the SH7619 The SH7619 does not support the following functions: • MMU-related functions (The SH7619 does not mount the MMU.
2.2.1 Break Condition Functions In the emulator, three break conditions can be set (Break Condition 1,2,3). Table 2.3 lists the items that can be specified for each. Table 2.3 Types of Break Conditions Break Condition Type Description Address bus condition (Address) Breaks when the SH7619 address bus value or the program counter value matches the specified value. Data bus condition (Data) Breaks when the SH7619 data bus value matches the specified value.
Table 2.4 lists the combinations of conditions that can be set under Break Condition 1,2,3. Table 2.4 Dialog Boxes for Setting Break Conditions Type Dialog Box Address Bus Condition (Address) Data Bus Condition (Data) Bus State Condition (Bus Status) Count Condition (Count) Internal I/O Break [Break Condition 1] dialog box O O O O X [Break Condition 2] dialog box O X O X X [Break Condition 3] dialog box X X X X O Note: O: Can be set in the dialog box.
3. Trace information cannot be acquired for the following branch instructions: • The BF and BT instructions whose displacement value is 0 • Branch to H'A0000000 by reset 2.2.3 4. When [User] is specified in the [UBC mode] list box in the [Configuration] window, the internal trace is not acquired. In this case, exit the [Trace] window. 5. When the SH7619 is used, the source code cannot be displayed on the [Trace] window.
8. If an address of a BREAKPOINT cannot be correctly set in the ROM or flash memory area, a mark z will be displayed in the [BP] area of the address on the [Editor] or [Disassembly] window by refreshing the [Memory] window, etc. after Go execution. However, no break will occur at this address. When the program halts with the break condition, the mark z disappears. 2.2.5 Notes on Setting the [Break Condition] Dialog Box and BREAKCONDITION_SET Command 1.
