CS/WD - Cyclic Sense or Watchdog prescaler select
This write-only bit selects which prescaler is being written to
the Cyclic Sense/Forced Wake-up prescaler or the Watchdog
prescaler.
1 = Cyclic Sense/Forced Wake-up Prescaler selected
0 = Watchdog Prescaler select

This write-only bits selects the divider for the watchdog
prescaler and therefore selects the watchdog period in
accordance with Table 23 . This configuration is valid only if
windowing watchdog is active.

CYSTx - Cyclic Sense Period Prescaler Select
This write-only bits selects the interval for the wake-up cyclic
sensing together with the bit CYSX8 in the Configuration
Register (CFR) (see Configuration Register - CFR on page
45 ).
This option is only active if the high side switch is enabled
when entering in Stop or Sleep mode. Otherwise a timed
wake-up is performed after the period shown in Table 24 .
This read-only bit signals the last reset was caused by either
a watchdog timeout or by an attempt to clear the Watchdog
within the window closed.
Any access to this register or the Timing Control Register
(TIMCR) will clear the WDTO bit.
1 = Last reset caused by watchdog timeout
0 = None
WDERR - Watchdog Error
This read-only bit signals the detection of a missing watchdog
resistor. In this condition the watchdog is using the internal,
lower precision timebase. The Windowing function is
disabled.
1 = WDCONF pin resistor missing
0 = WDCONF pin resistor not floating
