Data Memory
The data memory area consists of 8 banks and each bank has 256 nibbles (256 4 bits).
The data RAM is assigned to BANK 7 and peripheral ports are assigned to BANK 0.
Data Memory Map
Half the data RAM area (128 nibbles) is shared by the stack area. The stack is a memory starting
from address 7FFH toward the low-order addresses where 4 nibbles are used by Subroutine Call
Instruction and 8 nibbles are used by an interrupt.
The addresses 080H to 0FFH of BANK 0 are not assigned as the data memory, so access to these
addresses has no effect. Moreover, it is impossible to access BANK 1 to BANK 6.
