The RTCC includes a power control feature that allows
the device to periodically wake-up an external device,
wait for the device to be stable before sampling wake-up
events from that device and then shut down the external
device. This can be done completely autonomously by
the RTCC, without the need to wake from the current
low-power mode (Sleep, Deep Sleep, etc.).
To enable this feature, the RTCC must be enabled
(RTCEN = 1), the PWCEN register bit must be set and
the RTCC pin must be driving the PWC control signal
(RTCOE = 1 and RTCSECSEL<1:0> = 11).

The polarity of the PWC control signal may be chosen
using the PWCP register bit. Active-low or active-high
may be used with the appropriate external switch to
turn on or off the power to one or more external
devices. The active-low setting may also be used in
conjunction with an open-drain setting on the RTCC
pin. This setting is able to drive the GND pin(s) of the
external device directly (with the appropriate external
V
switches. Finally, the CHIME bit should be set to enable
the PWC periodicity.
