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.
Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and
Day of Year.
Programmable Reference Clock Divider allows adjustment of the RTC to match
various crystal frequencies.
6.19 Pulse width modulator
The PWM is based on the standard Timer block and inherits all of its features,
although only the PWM function is pinned out on the LPC2212/LPC2214. The Timer
is designed to count cycles of the peripheral clock (PCLK) and optionally generate
interrupts or perform other actions when specified timer values occur, based on
seven match registers. The PWM function is also based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to
be used for more applications. For instance, multi-phase motor control typically
requires three non-overlapping PWM outputs with individual control of all three pulse
widths and positions.
