Four 32-bit capture channels per timer that can take a snapshot of the timer value
when an input signal transitions. A capture event may also optionally generate an
interrupt.
Four 32-bit match registers that allow:
–
Continuous operation with optional interrupt generation on match.
–
Stop timer on match with optional interrupt generation.
–
Reset timer on match with optional interrupt generation.
Four external outputs per timer corresponding to match registers, with the following
capabilities:
–
Set LOW on match.
–
Set HIGH on match.
–
Toggle on match.
–
Do nothing on match.
6.17 Watchdog timer
The purpose of the Watchdog is to reset the microcontroller within a reasonable
amount of time if it enters an erroneous state. When enabled, the Watchdog will
generate a system reset if the user program fails to ‘feed’ (or reload) the Watchdog
within a predetermined amount of time.
6.17.1
Features
Internally resets chip if not periodically reloaded.
Debug mode.
Enabled by software but requires a hardware reset or a Watchdog reset/interrupt to
be disabled.
Incorrect/Incomplete feed sequence causes reset/interrupt if enabled.
Flag to indicate Watchdog reset.
Programmable 32-bit timer with internal pre-scaler.

6.18 Real time clock
The Real Time Clock (RTC) is designed to provide a set of counters to measure time
when normal or idle operating mode is selected. The RTC has been designed to use
little power, making it suitable for battery powered systems where the CPU is not
running continuously (Idle mode).
6.18.1
Features
Measures the passage of time to maintain a calendar and clock.
Ultra Low Power design to support battery powered systems.
