MOVWI
Move W to INDFn
Syntax:
[ label ] MOVWI ++FSRn
[ label ] MOVWI --FSRn
[ label ] MOVWI FSRn++
[ label ] MOVWI FSRn--
[ label ] MOVWI k[FSRn]
Operands:

-32
k 31
Operation:
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
Status Affected:
None

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.
The increment/decrement operation on
FSRn WILL NOT affect any Status bits.

OPTION
Load OPTION_REG Register
with W
Syntax:
[ label ] OPTION
Operands:
None
Operation:
(W)
OPTION_REG
Status Affected:
None
Description:
Move data from W register to
OPTION_REG register.
Words:
1
Cycles:
1
Example:
OPTION
Before Instruction
OPTION_REG = 0xFF
W = 0x4F
After Instruction
OPTION_REG = 0x4F
W = 0x4F
RESET
Software Reset
Syntax:
[ label ] RESET
Operands:
None
Operation:
Execute a device Reset. Resets the
RI flag of the PCON register.
Status Affected:
None
Description:
This instruction provides a way to
execute a hardware Reset by soft-
ware.
