MOV [using Expressions]

MOV W,/fr Move not fr into W

Words: 1 Cycles: 1 Affects: Z

Operation: The oneâ€™s complement of fr is moved into W. Z will be set to 1 if the result was 0, otherwise Z will cleared to 0.

Coding: COMF fr,0

MOV W,fr-W Move fr-W into W

Words: 1 Cycles: 1 Affects: C, DC, Z

Operation: W is subtracted from fr and the result is stored in W. C will be cleared to 0 if an underflow occurred, otherwise C will be set to 1. DC will be cleared or set depending on whether or not an underflow occurred in the least-significant nibble. Z will be set to 1 if the result was 0, otherwise Z will be cleared to 0.

Coding: SUBWF fr,0

MOV W,++fr Move the incremented value of fr into W

Words: 1 Cycles: 1 Affects: Z

Operation: The incremented value of fr is moved into W. Z will be set to 1 if the result was 0, otherwise Z will be cleared to 0.

Coding: INCF fr,0

MOV W,--fr Move the decremented value of fr into W

Words: 1 Cycles: 1 Affects: Z

Operation: The decremented value of fr is moved into W. Z will be set to 1 if the result was 0, otherwise Z will be cleared to 0.

Coding: DECF fr,0

MOV W,<<fr Move the left-rotated value of fr into W

Words: 1 Cycles: 1 Affects: C

Operation: The left-rotated value of fr is moved into W. On entry, C must hold the value to be shifted into the least-significant bit of the fr value. On exit, C will hold the previous most-significant bit of the fr value.

Coding: RLF fr,0

MOV W,>>fr Move the right-rotated value of fr into W

Words: 1 Cycles: 1 Affects: C

Operation: The right-rotated value of fr is moved into W. On entry, C must hold the value to be shifted into the most-significant bit of the fr value. On exit, C will hold the previous least-significant bit of the fr value.

Coding: RRF fr,0

MOV W,<>fr Move the nibble-swapped value of fr into W

Words: 1 Cycles: 1 Affects: none

Operation: The nibble-swapped value of fr is moved into W.

Coding: SWAPF fr,0
