Chapter 5 Interrupts
FEUL62Q1000
5-37
5.3 Description of Operation
Enabling/disabling the maskable interrupt can be controlled by the master interrupt enable flag (MIE) of the CPU and
each interrupt enable register (IE1 to 7).
A watchdog timer interrupt (WDTINT) is unavailable to disable as it is a non-maskable interrupt.
When interrupt conditions are satisfied, the CPU calls a branching destination address from the vector table determined
for each interrupt source and the interrupt transfer cycle starts to branch to the interrupt processing routine.
If multiple interrupts are generated concurrently when the interrupt level control function is disabled, they are processed
starting from the interrupt with the highest priority (with a smallest interrupt source number). The lower- priority
interrupts (with larger interrupt source numbers) remain pending.
If multiple interrupts are generated concurrently when the interrupt level control function is enabled, they are processed
starting from the interrupt with both the highest interrupt level and the highest priority level. The lower- priority
interrupts remain pending.
Table 5-2 lists the interrupt sources.
The interrupt vector address is an address of the interrupt vector defined in the program memory. See "nX-U16/100 Core
Instruction Manual" for details of the interrupt vector address.
