FUNCTIONAL DEVICE OPERATIONS
LOGIC COMMANDS AND REGISTERS
Timing Control Register - TIMCR
This register is a double purpose register which allows to
configure the watchdog and the cyclic sense periods. Writing
to the Timing Control Register (TIMCR) will also return the
Watchdog Status Register (WDSR).
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 54 .

This write-only bit selects which prescaler is being written to,
the Cyclic Sense prescaler or the watchdog prescaler.

This write-only bits selects the divider for the watchdog
prescaler and therefore selects the watchdog period in
accordance with Table 53 . 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 ).
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 TIMCR will clear the WDTO
bit.
1 = Last reset caused by watchdog timeout
0 = None
