The purpose of the watchdog is to reset the controller if software fails to periodically
service it within a programmable time window.

32-bit compare mask. An interrupt is generated when the counter value equals the
compare value, after masking. This allows for combinations not possible with a simple
compare.
Internally resets chip if not periodically reloaded during the programmable time-out
period.
Optional windowed operation requires reload to occur between a minimum and
maximum time period, both programmable.
Optional warning interrupt can be generated at a programmable time prior to
watchdog time-out.
Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
Incorrect feed sequence causes reset or interrupt if enabled.
Flag to indicate watchdog reset.
Programmable 24-bit timer with internal prescaler.
Selectable time period from (T
multiples of T
The Watchdog Clock (WDCLK) uses the IRC as the clock source.
10-bit successive approximation analog to digital converter.
Input multiplexing among 8 pins.
Power-down mode.
Measurement range 0 to 3 V.
Sampling frequency up to 400 kSamples/s.
Burst conversion mode for single or multiple inputs.
Optional conversion on transition on ADCTRIG0 or ADCTRIG1 pins, combined timer
outputs 8 or 15, or the PWM output MCOA2.
Individual result registers for each A/D channel to reduce interrupt overhead.
DMA support.
10-bit resolution
