Register Name:
Access Type:
Backup Reset Value:0x1
Offset:
• SHDALS: Shut-down or Alarm Output Selection
This field defines the state of the SHDAL pin when shut-down or alarm is requested.
• WKACKS: Wake-up or Alarm Acknowledge Output Selection
This field defines the state of the WKACKS pin when wake-up or alarm acknowledge is requested.
• ALWKEN: Alarm Wake-up Enable (Code Label APMC_WKEN)
0 = The alarm from the RTC has no wake-up effect.
1 = The alarm from the RTC commands a wake-up.
• ALSHEN: Alarm Shut-down Enable (Code Label APMC_ALSHEN)
0 = The alarm from the RTC has no shut-down effect.
1 = If ALWKEN is 0, the alarm from the RTC commands a shut-down.
