Processing details
• This instruction enables or disables the execution of the interrupt program with the interrupt pointer number specified by the
16 points of bit pattern starting from the device specified by (s).
• 1 (on): Enables the execution of the interrupt program.
• 0 (off): Disables the execution of the interrupt program.
• The interrupt pointer numbers correspond to individual bits as shown below.

• When the system is powered on or the CPU module is reset, the execution of interrupt programs I0 to I31 and I44 to I1023
is enabled and the execution of interrupt programs I32 to I43 is disabled.
• The states of the device range (s) to (s)+15 are stored in SD1400 to SD1463.
The IMASK instruction can enable or disable the execution of interrupt pointers I0 to I255 altogether.
To enable or disable the execution of interrupt pointers I256 to I1023, substitute the SIMASK instruction for the
IMASK instruction in the program.
For details on the SIMASK instruction, refer to the following.
