Program Memory Map

Address 000H is the instruction execution start address by the system reset.

The CZP area from address 010H to address 01FH 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 020H

to 03DH.

The user area has 2016 bytes of address 000H to address 07DFH. No program can be stored in

the test program area.
