Description
Indicates when the watchdog timer has expired (overflowed).
One second pulse with 25% Duty Cycle. This signal can be used
to measure the deviation of the RTC from an ideal 1 second
interval. Multiple cycles should be averaged together to filter out
jitter.
Four second pulse with 25% Duty Cycle. This signal can be used
to measure the deviation of the RTC from an ideal 4 second
interval. Multiple cycles should be averaged together to filter out
jitter. The 4 second pulse provides a more precise measurement
than the 1 second pulse.
32.768 kHz clock waveform
Copies the value of the bit stored in 0x2704[1]. For general
purpose use.
Copies the value of the bit stored in 0x2704[2]. For general
purpose use.
Indicates when a WAKE event has occurred.
