is activated by a write access with any data to ALPR followed by a STOP instruction.
The sequence to enter sleep mode is as follows:
Sleep mode is exited by an interrupt request from by either an external device or an on-chip peripheral as
detailed in
The sequence to enter stop mode is:
Stop mode is exited by an interrupt request from an external device as detailed in
