MOVFP

Move f to p

Syntax:

[

label]

MOVFP f,p

Operands:

≤ f ≤ 255

≤ p ≤ 31

Operation:

(f)

→ (p)

Status Affected:

None

Encoding:

011p

pppp

ffff

Description:

Move data from data memory location 'f'

to data memory location 'p'. Location 'f'

can be anywhere in the 256 word data

space (00h to FFh) while 'p' can be 00h

to 1Fh.

Either ’p' or 'f' can be WREG (a useful

special situation).

MOVFP

is particularly useful for transfer-

ring a data memory location to a periph-

eral register (such as the transmit buffer

or an I/O port). Both 'f' and 'p' can be

indirectly addressed.

MOVLB

Move Literal to low nibble in BSR

Syntax:

[

label ]

MOVLB k

Operands:

≤ k ≤ 15

Operation:

→ (BSR<3:0>)

Status Affected:

None

Encoding:

1011

1000

uuuu

kkkk

Description:

The four bit literal 'k' is loaded in the

Bank Select Register (BSR). Only the

low 4-bits of the Bank Select Register

are affected. The upper half of the BSR

is unchanged. The assembler will

encode the “u” ﬁelds as '0'.

Execute

Write literal

'k' to

BSR<3:0>

Example:

MOVLB

0x5

Before Instruction

BSR register

0x22

After Instruction

BSR register

0x25

Note:

For the PIC17C42, only the low four bits of

the BSR register are physically imple-

mented. The upper nibble is read as '0'.
