[Description example]
[Illustration]
The 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 SFR
mapped at FF00H to FF1FH can be accessed with short direct addressing.
