Returning from Low Power Consumption Modes
The interrupt control unit is capable of returning operation from low power consumption modes in response to interrupts.
Table 10.5 shows the correspondence between low power consumption modes and the interrupt sources that are capable
of initiating return from the individual modes.

Returning from Sleep Mode and All-Module Clock Stop Mode
The interrupt control unit can return operation from sleep mode or all-module clock stop mode in response to any
interrupts.
The following conditions apply.
1.
The interrupt destination is the CPU.
2.
The given interrupt request is enabled by the IENj bit in IERi.
3.
The priority level of the interrupt is higher than that set by the IPL[2:0] bits in the PSW of the CPU.
