• The FMOV(P) instruction is a batch write instruction for a constant (K0 for example) that can write "0" for word devices
(including nibble specification of bit devices).
X2
FMOV K0 D0
(1): K0 is written to D0 to D99.
Precautions
• Specify the same type of device for (d1) and (d2) so that (d1) number is less than (d2) number. If the (d1) number(d2)
number, only the device specified by (d1) is reset.
• The ZRST(P) instruction is a 16-bit instruction, but long counter (LC) and long index register (LZ) can be specified for (d1)
and (d2).
