E8a Emulator Section 6 Notes on Using the E8a Emulator

5. SFRs used by the E8a emulator program

As the SFRs listed in Table 6.3 are used by the E8a emulator program, do not change any of these values. If these

values are changed, the E8a emulator cannot control the MCU. Note that UART1 transmit interrupt control register

S1TIC and UART1 receive interrupt control register S1RIC always read out values used by the emulator. These

registers are not initialized by selecting [Debug] -> [Reset CPU] or by using the RESET command. If register

contents are referred to, a value that has been set in the E8a emulator program will be read out.

Notes:

1. Do not change this register value.

2. Do not change the value of the bits listed in the column to the left. When operating this register, make changes using the

bit operation instructions to avoid changing the bit values.

6. Interrupts used by the E8a emulator program

REJ10J1640-0400

Rev.4.00 Page 15 of 31

The BRK instruction interrupt, address match interrupt, single-step interrupt and DBC interrupt are used by the

E8a emulator program. Therefore, make sure the user program does not use any of these interrupts. The E8a

emulator changes these interrupt vector values to the values to be used by the emulator. No problems occur if the

interrupt vector values are written in the user program.
