ANDsrc
LogicalAND
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 . Because the source field is limited
to 8 bits, the PFX[n] register is used to supply the high-byte of data for 16 bit sources .
StatusFlags:
S, Z
Operation:
Acc
← Acc AND src
Encoding:

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
SpecialNotes:
The active accumulator (Acc) is not allowed as the src for this operation .
ANDAcc.<b>
LogicalANDCarryFlagwithAccumulatorBit
Description:
Performs a logical-AND between the Carry (C) status flag and a specified bit of the active accumu-
lator (Acc .<b>) and returns the result to the Carry .
StatusFlags:
C
Operation:
C
← C AND Acc . <b>

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
