• The interrupt priority is the order which is executed at the time of the multiple interrupt. ( Page 81
Interrupt priority)
• The interrupt priority order is the order which is executed when the interrupt factor with the same interrupt
priority is generated. ( Page 84 Multiple interrupt execution sequence)

Description
This is a pointer used for modules which have the interrupt function.
This interrupt pointer is used in fixed scan interrupts by the internal timer.
This fixed scan interrupt pointer is used in the inter-module synchronization
function.
This fixed scan interrupt pointer is used in the multiple CPU synchronization
function.
This interrupt pointer is used in fixed scan interrupts by the internal timer
and can be specified in a shorter interval than interrupt pointer numbers I28
to I31.
This is a pointer used for modules which have the interrupt function.
