Operation: (W) AND k -> W
Operand: 0 ≤ k ≤ 255
Status affected: Z
Number of cycles: 1
EXAMPLE 1:
....
[label] ANDLW 0x5F
Before instruction execution: W = 0xA3 ; 1010 0011 (0xA3)
; 0101 1111 (0x5F)
------------------
After instruction: W = 0x03 ; 0000 0011 (0x03)
Z = 0 (result is not 0)
EXAMPLE 2:
....
[label] ANDLW 0x55
Before instruction execution: W = 0xAA ; 1010 1010 (0xAA)
; 0101 0101 (0x55)
------------------
After instruction: W = 0x00 ; 0000 0000 (0x00)
Z = 1( result is 0)
ANDWF - AND W with f
Syntax: [label] ANDWF f,d
Description: AND the W register with register f.
If d = w or d = 0, the result is stored in the W register.
If d = f or d = 1, the result is stored in register f.
