-32 ≤ k ≤ 31
If not present, k = 0.
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

Postdecrement INDFn--
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.
FSRn is limited to the range 0000h -
FFFFh. Incrementing/decrementing it
beyond these bounds will cause it to wrap
around.
The increment/decrement operation on
FSRn WILL NOT affect any Status bits.
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).
MOVLP
Syntax:
Operands:
Operation:
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.
MOVLW

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.
