8.2 List of Special Function Registers

Note: The register address can be bit-addressable only if it is divisible by 8, and it cannot be bit-addressable if it is not

divisible by 8.

Registers in STC8A8K64D4 which can be bit-addressable are: P0 (80H), TCON (88H), P1 (90H), SCON (98H), P2 (A0H),

IE (A8H), P3 (B0H), IP (B8H), P4 (C0H), P5 (C8H), PSW (D0H), ACC (E0H), B (F0H)
