E8a Emulator
6. Notes on Using the E8a Emulator
(4) SFRs used by the E8a emulator program
The SFRs listed in Tables 6.3 and 6.4 are used by the E8a emulator program, not the user program.
- Do not change the registers, otherwise the E8a cannot control the MCU.
- The SFRs listed in Tables 6.3 and 6.4 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
[*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.
[*3] UART1 transmit interrupt control register S1TIC and UART1 receive interrupt control register S1RIC always read
out values used by the emulator.
