[ label ] MOVWI k[FSRn]
n  [0,1].
-32  k  31
If not present, k = 0.
W  INDFn
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
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.
The increment/decrement operation on
FSRn WILL NOT affect any Status bits.
