Rev. 3.6
18/34
Status Affected
Z
Description
M (f) is decremented. If d is 0, the result is stored in the W register. If d is 1, the
result is stored back in M (f).
DECFSZ
Decrement f, skip if zero
Syntax
DECFSZ f, d
Operation
M (f) - 1 => (destination), skip if result is zero
Status Affected
None
Description
M (f) is decremented. If d is 0, the result is stored in the W register. If d is 1, the
result is stored back in M (f). If the result is 0, then the next fetched instruction is
discarded and a NOP is executed instead making it a two-cycle instruction.
SUBWF
Subtract W from f
Syntax
SUBWF f, d
Operation
M (f) + NOT (W) + 1 => (destination)
Status Affected
DC, C, Z
Description
Subtract the content of the W register from M (f). If d is 0, the result is stored in the
W register. If d is 1, the result is stored back in M (f),
COMF
Complement f
Syntax
COMF f, d
Operation
NOT (M (f)) => M (f)
Status Affected
Z
Description
M (f) is complemented. If d is 0, the result is stored in the W register. If d is 1, the
result is stored back in M (f)
MOVWF
Move W to f
Syntax
MOVWF f
Operation
W => M (f)
Status Affected
None
Description
Move data from the W register to M (f).
MOVFW
Move f to W
Syntax
MOVFW f
Operation
M (f) => W
Status Affected
None
Description
Move data from M (f) to the W register.
ADDWFC
Add W, f and Carry
Syntax
ADDWFCf, d
Operation
W + M (f) + C => (destination)
Status Affected
DC, C, Z
Description
Add the content of the W register, M (f) and Carry bit. If d is 0, the result is stored
in the W register. If d is 1, the result is stored back in M (f).
ANDWF
And W and f
Syntax
ANDWF f, d
Operation
W AND M (f) => (destination)
Status Affected
Z
Description
AND the content of the W register with M (f). If d is 0, the result is stored in the W
register. If d is 1, the result is stored back in M (f).
IORWF
Inclusive OR W and f
Syntax
IORWFf, d
Operation
W OR M (f) => (destination)
Status Affected
Z
Description
Inclusive OR the content of the W register and M (f). If d is 0, the result is stored in
