Interrupt Control

This section describes how to enable or disable maskable interrupts and how to set the priority to be

accepted. The discussion here does not apply to non-maskable interrupts.

Maskable interrupts are enabled or disabled using the interrupt enable flag (I flag), the interrupt priority

level selection bit, and the processor interrupt priority level (IPL). Whether an interrupt request is present

or absent is indicated by the interrupt request bit. The interrupt request bit and the interrupt priority level

selection bit are located in the interrupt control register of each interrupt. Also, the interrupt enable flag (I

flag) and the IPL are located in the flag register (FLG).

Figure 1.9.3 shows the configuration and memory map of the interrupt control registers.
