Processing details
• This instruction turns off the annunciator specified by (d) when the execution command turns on.
• The annunciator number (F number) turned off is deleted from the special register (SD64 to SD79), and the value in SD63
is decremented by one.

an annunciator with a number not registered in SD64 to SD79 has been turned on, the number is newly registered. If all
annunciator numbers in SD64 to SD79 are reset (turned off), the USER LED of the CPU module turns off.
