Page Addressing
A. SFR Page Addressing: sfr Dadr
B. FIXED Page Addressing: fix Dadr
C. Current Page Addressing: off Dadr
A. SFR Page Addressing
SFR page addressing specifies an offset in the SFR page (0–0FFH in data memory)
with one byte of instruction code. Word, byte, or bit data can be accessed at the
specified address.
The operand is coded with the "sfr" addressing specifier. The "sfr" can be omitted, but
then SFR page addressing will only be used when the assembler recognizes that an
address is in the SFR page.
Every microcontroller device has its particular SFR symbols (abbreviated names).
Normally these symbols are used for SFR accesses.
If an odd address is specified, then the word data starting at the next lower even
address will be accessed (see "Word Operation"). However, there are exceptions
depending on the SFR.
