Processing details
• This instruction enables or disables the execution of the interrupt program with the interrupt pointer number specified by (I)
according to the data specified by (s)
• When 1 is set in (s): The execution of the interrupt program is enabled.
• When 0 is set in (s): The execution of the interrupt program is disabled.
• When the power is turned on or the CPU module is reset, the execution status of the interrupt programs of I0 to I177 is
applied.
• The execution-enabled/disabled states of interrupt pointers are stored in SD1400 to 1415 (IMASK instruction mask
pattern).
Operation error
Error code Description
(SD0/SD8067)
3405H The interrupt pointer number specified by (I) exceeds the range of the interrupt pointer number (I0 to I177).
The value in (s) is other than the interrupt disabled (0) or interrupt enabled (1).
