Status Affected:
Move INDFn to W
[ label ] MOVIW ++FSRn
[ label ] MOVIW --FSRn
[ label ] MOVIW FSRn++
[ label ] MOVIW FSRn--
[ label ] MOVIW k[FSRn]
n  [0,1]
mm  [00,01, 10, 11]
-32  k  31
INDFn  W
Effective address is determined by
• FSR + 1 (preincrement)
• FSR - 1 (predecrement)
• FSR + k (relative offset)
After the Move, the FSR value will be
either:
• FSR + 1 (all increments)
• FSR - 1 (all decrements)
• Unchanged

Description:
This instruction is used to move data
between W and one of the indirect
registers (INDFn). Before/after this
move, the pointer (FSRn) is updated by
pre/post incrementing/decrementing it.
Note: The INDFn registers are not
physical registers. Any instruction that
accesses an INDFn register actually
accesses the register at the address
specified by the FSRn.
FSRn is limited to the range 0000h -
FFFFh. Incrementing/decrementing it
beyond these bounds will cause it to
wrap-around.
MOVLB
Syntax:
Operands:
Operation:
Status Affected:
Description:
Move literal to BSR
[ label ] MOVLB k
0  k  15
k  BSR
None
The five-bit literal ‘k’ is loaded into the
Bank Select Register (BSR).

Status Affected:
Description:
Move literal to PCLATH
[ label ] MOVLP k
0  k  127
k  PCLATH
None
The seven-bit literal ‘k’ is loaded into the
PCLATH register.

Example:
Move literal to W
[ label ] MOVLW k
0  k  255
k  (W)
None
The eight-bit literal ‘k’ is loaded into W
register. The “don’t cares” will assem-
ble as ‘0’s.
