Preliminary

MOVF

Move f

Syntax:

[

label ]

MOVF f,d

Operands:

≤ f ≤ 31

∈ [0,1]

Operation:

(f)

→ (dest)

Status Affected:

Encoding:

0010

00df

ffff

Description:

The contents of register 'f' is moved to

destination 'd'. If 'd' is 0, destination is

the W register. If 'd' is 1, the destination

is ﬁle register 'f'. 'd' is 1 is useful to test

a ﬁle register since status ﬂag Z is

affected.
