INTERRUPTS
4.3 Interrupt control
4.3 Interrupt control
The enabling and disabling of maskable interrupts are controlled by the following :
•Interrupt request bit
•Interrupt priority level select bits
•Processor interrupt priority level (IPL)
•Interrupt disable flag (I)
The interrupt disable flag (I) and the processor interrupt priority level (IPL) are assigned to the processor
Figure 4.3.1 shows the memory assignment of the interrupt control registers, and Figure 4.3.2 shows their

Maskable interrupt: An interrupt of which request’s acceptance can be disabled by software.
Non-maskable interrupt (including Zero division, BRK instruction, Watchdog timer interrupts):
An interrupt which is certain to be accepted when its request occurs. These interrupts do not have their
interrupt control registers and are independent of the interrupt disable flag (I).
