f : memory address ( 0h ~ FFh)
w: work register
k : literal field , constant data or label
d: destination select : d=0 store result in W, d=1: store result in memory address f.
b: bit select(0~7)
M(f): the content of memory address f
PC: program counter
11.1.6 Instruction Description
NOP
No Operation
Syntax
NOP
Operation
No Operation
Status Affected
None
Description
No operation. NOP is used for one instruction cycle delay.
CLRF
Clear f
Syntax
CLRF f
Operation
0 => M (f)
Status Affected
1=> Z
Description
Reset memory address f content.
ADDWF
Add W to f
Syntax
ADDWF f, d
Operation
W + M (f) => (destination)
Status Affected
DC, C, Z
Description
Add the content of the W register and 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).
INCF
Increment f
Syntax
INCF
f, d
Operation
M (f) + 1 => (destination)
Status Affected
Z
Description
M (f) is incremented. If d is 0, the result is stored in the W register. If d is 1, the
result is stored back in M (f).
INCFSZ
Increment f, skip if zero
Syntax
INCFSZ f, d
Operation
M (f) + 1 => (destination), skip if result is zero
Status Affected
None
Description
M (f) is incremented. 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.
DECF
Decrement f
Syntax
DECF f, d
Operation
M (f) - 1 => (destination)
