3.4.5 Special function register (SFR) addressing
86
Effective address
[Function]
[Operand format]
[Description example]
A memory-mapped special function register (SFR) is addressed with 8-bit immediate data in an instruction word.
This addressing is applied to the 240-byte spaces FF00H to FFCFH and FFE0H to FFFFH. However, the SFRs
mapped at FF00H to FF1FH can be accessed with short direct addressing.
