2.15 Multiple interrupts Usage
Figure 2.15.1. Memory map of the interrupt control registers
2.15.1 Overview of the Multiple interrupts usage
The following is an overview of the multiple interrupts usage.
(1) Interrupt control
Descriptions are given here regarding how to enable or disable maskable interrupts and how to set the
priority to be accepted. What is described here does not apply to non-maskable interrupts.
Enable or disable a non-maskable interrupt using the interrupt enable flag (I flag), interrupt priority
level selection bit, or 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
select 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 2.15.1 shows the memory map of the interrupt control registers, and Figure 2.15.2 shows the
interrupt control registers.
