Program Memory Map
Address 0000H is the instruction execution start address by the system reset.
The CZP area from address 0010H to address 001FH is the start address for the CZP subroutine of 1-byte
call instruction.
The start address of interrupt subroutine is assigned to the interrupt address from address 0020H to
003DH.
The user area has 8160 bytes of address 0000H to 1FDFH. No program can be stored in the test program
area.
