• WKUPEN0 - WKUPEN15: Wake Up Input Enable 0 to 15
0 (NOT_ENABLE) = the corresponding wake-up input has no wake up effect.
1 (ENABLE) = the corresponding wake-up input forces the wake up of the core power supply.
• WKUPT0 - WKUPT15: Wake Up Input Transition 0 to 15
0 (HIGH_TO_LOW) = a high to low level transition on the corresponding wake-up input forces the wake up of the core
power supply.
1 (LOW_TO_HIGH) = a low to high level transition on the corresponding wake-up input forces the wake up of the core
power supply.
