12.5 Return from Standby (Stop or Sleep) Mode
This module implements the function that enables a return from the stop mode
through interrupts. Return from Standby (Stop or Sleep) Mode.
I Return from standby (stop or sleep) mode
If at least one interrupt request is issued from a peripheral, the request for returning from the
stop mode is sent to the clock control block.
Since the priority evaluation block restarts operation after the clock signal is supplied upon
return from stop mode, the CPU continues executing instructions until the result is output from
the priority evaluation block.
The same operation is performed when returning from the sleep state.
The registers in this module are accessible in the sleep state.
Note:
•
For interrupt sources you do not want to use to return from the stop and sleep states, set the
control register for the corresponding peripheral to prohibit the interrupt request output. Since
the return request signal in the standby state is generated by simply logical sum of all
interrupt sources, the contents of the interrupt level specified in ICR are not applied.
