27.13 Interrupt Pointer (I)
The priority for the interrupt pointer numbers and interrupt
factors
The priority for the interrupt pointer numbers and interrupt factors are indicated.
• The interrupt priority is the order which is executed at the time of the multiple interrupt. ( Page 129
Interrupt priority)
• The interrupt priority order is the order which is executed when the interrupt factor with the same interrupt
priority is generated. ( Page 132 Multiple interrupt execution sequence)
