6.3 Interrupt control
The maskable interrupts are controlled by the following :
•Interrupt request bit
•Interrupt priority level select bits
•Processor interrupt priority level (IPL)
•Interrupt disable flag (I)
Figure 6.3.1 shows the memory assignment of the interrupt control registers, and Figures 6.3.2 shows their
