AND
src
Logical AND
Description:
Performs a logical-AND between the active accumulator (Acc) and the specified src data. For the complete list of
src specifiers, reference the MOVE instruction. The MAXQ7665/MAXQ7666 may use the PFX[n] register to supply
the high byte of data for 8-bit sources.
Status Flags:
S, Z
Operation:
Acc
← Acc AND src
Encoding:
15
0
Example(s):
; Acc = 2345h for each example
AND A[3]
; A[3]=0F0Fh
;
→ Acc = 0305h, S=0, Z=0
AND #33h
;
→ Acc = 0001h
AND #2233h
; generates object code below
; MOVE PFX[0], #22h (smart-prefixing)
; AND #33h
;
→ Acc = 2201h
MOVE PFX[0], #0Fh
AND M0[8]
; M0[8]=0Fh (assume M0[8] is an 8-bit register)
;
→ Acc = 0305h
Special Notes:
The active accumulator (Acc) is not allowed as the src for this operation.

Example(s):
; Acc = 2345h, C=1 at start
AND Acc.0
; Acc.0=1
→ C=1
AND Acc.1
; Acc.1=0
→ C=0
AND C, Acc.8
; Acc.8=1
→ C=0
