4.7.1 Change in IPL at acceptance of interrupt request
When an interrupt request is accepted, the processor interrupt priority level (IPL) is replaced with the
interrupt priority level of the accepted interrupt. This results in easy control of multiple interrupts. (Refer
to section “4.9 Multiple interrupts.”)
When at reset or the watchdog timer or the software interrupt is accepted, the value shown in Table 4.7.1
is set in the IPL.
