ADDRESS SPACES
WORKING REGISTERS
Working registers, mapped to RAM address 000H–01FH in data memory bank 0, are used to temporarily store
intermediate results during program execution, as well as pointer values used for indirect addressing. Unused
registers may be used as general-purpose memory. Working register data can be manipulated as 1-bit units, 4-bit
units or, using paired registers, as 8-bit units.
