Interrupt program mask
IMASK
This instruction enables or disables the execution of the interrupt program with the specified interrupt pointer number
according to the 16-point bit pattern starting from the device specified in (s).
■Descriptions, ranges, and data types
■Applicable devices
• This instruction enables or disables the execution of the interrupt program with the specified interrupt pointer number
according to the 16-point bit pattern starting from the device specified in (s).
• The following shows the assignment of the interrupt pointer numbers to each bit.
• When the power is turned on or the CPU module is reset, execution status of the interrupt programs of I0 to I177 is applied.
• The states of the device (s) to (s)+15 are stored in SD1400 to SD1415 (IMASK instruction mask pattern).
