Multiple Interrupts
2.14.2 Multiple Interrupts Operation
The state when control branched to an interrupt routine is described below:
Setting the interrupt enable flag (I flag) to “1” within an interrupt routine allows an interrupt request as-
signed a priority higher than the IPL to be accepted.
An interrupt request that is not accepted because of low priority will be held. If the condition following is
met when the REIT instruction returns the IPL and the interrupt priority is determined, then the interrupt
request being held is accepted.
Figure 2.14.6 shows the example of the multiple interrupts operation.
· The interrupt enable flag (I flag) is set to “0” (the interrupt is disabled).
· The interrupt request bit of the accepted interrupt is set to “0”.
· The processor interrupt priority level (IPL) is assigned to the same interrupt priority level as as
Interrupt priority level of the interrupt request being held
signed to the accepted interrupt.
