Write to W
Example:
MOVLW 0x5A
After Instruction
W = 0x5A
MOVWF Move W to f
Syntax: [ label ] MOVWF f [,a]
Operands: 0 ≤ f ≤ 255
a ∈ [0,1]
Operation: (W) → f
Status Affected: None
Encoding:
0110 111a ffff ffff
Description: Move data from W to register ‘f’.
Location ‘f’ can be anywhere in the
256-byte bank. If ‘a’ is ‘0’, the
Access Bank will be selected,
overriding the BSR value. If ‘a’ = 1,
then the bank will be selected as
per the BSR value (default).
