PIC16C62X
MOVF Move f
Syntax: [ label ] MOVF f,d
Operands: 0 ≤ f ≤ 127
d ∈ [0,1]
Operation: (f) → (dest)
Status Affected: Z
Encoding:
00 1000 dfff ffff
Description: The contents of register f is
moved to a destination dependent
upon the status of d. If d = 0,
destination is W register. If d = 1,
the destination is file register f
itself. d = 1 is useful to test a file
register since status flag Z is
affected.

Example
MOVF FSR,

After Instruction
W = value in FSR
register
Z= 1
MOVWF Move W to f
Syntax: [ label ] MOVWF f
Operands: 0 ≤ f ≤ 127
Operation: (W) → (f)
Status Affected: None
Encoding:
00 0000 1fff ffff
Description: Move data from W register to reg-
ister 'f'.

Example
MOVWF OPTION
Before Instruction
OPTION = 0xFF
W = 0x4F
After Instruction
OPTION = 0x4F
W = 0x4F
NOP No Operation
Syntax: [ label ] NOP
Operands: None
Operation: No operation
Status Affected: None
Encoding:
00 0000 0xx0 0000
Description: No operation.

NOP
OPTION Load Option Register
Syntax: [ label ] OPTION
Operands: None
Operation: (W) → OPTION
Status Affected: None
Encoding:
00 0000 0110 0010
Description: The contents of the W register are
loaded in the OPTION register.
This instruction is supported for
code compatibility with PIC16C5X
products. Since OPTION is a read-
able/writable register, the user can
directly address it.

To maintain upward compatibil-
ity with future PICmicro

products, do not use this
instruction.
