A.
The WDRST signal is driven low for 512 OSCCLK cycles.
Figure 3-10. Watchdog Module
The WDINT signal enables the watchdog to be used as a wakeup from IDLE/STANDBY mode.
In STANDBY mode, all peripherals are turned off on the device. The only peripheral that remains
functional is the watchdog. The WATCHDOG module will run off OSCCLK. The WDINT signal is fed to the
LPM block so that it can wake the device from STANDBY (if enabled). See Section
Section 3.7
,
Low-Power Modes Block, for details.
In IDLE mode, the WDINT signal can generate an interrupt to the CPU, via the PIE, to take the CPU out of
IDLE mode.
In HALT mode, this feature cannot be used because the oscillator (and PLL) are turned off and hence so
is the WATCHDOG.
