3. The E8a emulator communicates with the MCU by using the MODE and RESET pins.
4. The E8a emulator uses up to 8 bytes of the stack pointer during a user program break. Therefore, set aside 8 bytes
for the stack area.
5. Peripheral function used by the E8a emulator program
UART1 is used by the E8a emulator. Do not use UART1 in the user program.
