Processing details
• These instructions store the total bits of 1 in the binary 32-bit data of the device specified by (s) to the device specified by
(d).
• When all binary 32-bit data of the device specified by (s) are 0 (off), the zero flag M8020 turns on.
Precautions
While the command input is off, the instruction is not executed. The output of the number of bits in the on status is latched in
the previous status.
