10.3.2 Data Memory Organization
The data memory is partitioned into three parts. The address 00H~07H areas are system special registers, like
indirect address, indirect address pointer, status register, working register, interrupt flag and interrupt control
register. The address 08H~1FH areas are peripheral special registers. The address 80H~BFH areas are general
data memory.

08H~1FH
80H~BFH
IND0, IND1
The IND[1:0] registers at data memory address are not physical registers. Any instruction using the IND[1:0]
registers actually access the data pointed by the FSR[1:0] registers.
bit7~0
FSR0, FSR1
Indirect addressing pointers FSR0 and FSR1 correspond to IND0 and IND1 respectively.

STATUS
The STATUS register contains the arithmetic status of the ALU.
