Absolute Boolean Bit is used on the SPC700 by some instructions to address individual bits:

The bottom 13 bits of a 16-bit value specify an absolute address, while the top 3 bits specify which bit within the byte stored at that address. The greatest address these instructions can affect is 1FFFh.

Syntax

AND1 C, mem. bit
AND1 C, /mem. bit
OR1 C, mem. bit
OR1 C, /mem. bit
EOR1 C, mem. bit
MOV1 C, mem. bit
MOV1 mem. bit, C
NOT1 mem. bit
