In Partial IO, I/O pins and small logics in the CANUART I/O Bank are active, and the rest of the SoC is turned off. The user can use the I/O pins to aggregate multiple I/O wakeup events and toggle PMIC_LPM_EN pin to enable PMIC or discrete power solution when an I/O wakeup event is triggered. The information on the I/O wakeup event is logged in the MMR in the CANUART I/O bank and helps the software to distinguish between cold boot and wakeup to respond to the wakeup event faster.
