MOVWF

Move WREG to f

Syntax:

[ label ] MOVWF f [,a]

Operands:

0 ≤ f ≤ 255

a ∈ [0,1]

Operation:

(WREG) → f

Status Affected: None

Encoding:

Description:

Move data from WREG to register

’f’. Location ’f’ can be anywhere in

the 256 byte Bank. If ’a’ is 0, the

Access Bank will be selected, over-

riding the BSR value. If ’a’ is 1, the

Bank will be selected as per the

BSR value.
