Q1

Decode

Move W to f

MOVWF f {,a}

0 ≤ f ≤ 255

a ∈ [0,1]

(W) → f

None

0110 111a ffff ffff

Move data from W to register ‘f’.

Location ‘f’ can be anywhere in the

256-byte bank.

If ‘a’ is ‘0’, the Access Bank is selected.

If ‘a’ is ‘1’, the BSR is used to select the

GPR bank (default).

If ‘a’ is ‘0’ and the extended instruction

set is enabled, this instruction operates

in Indexed Literal Offset Addressing

mode whenever f ≤ 95 (5Fh). See

Section 24.2.3 “Byte-Oriented and

Bit-Oriented Instructions in Indexed

Literal Offset Mode” for details.
