7.16.1 Integrated oscillators
7.16 Clocking and power control
The LPC11E1x include three independent oscillators: the system oscillator, the Internal
RC oscillator (IRC), and the watchdog oscillator. Each oscillator can be used for more
than one purpose as required in a particular application.
Following reset, the LPC11E1x operates from the internal RC oscillator until software
switches to a different clock source. The IRC allows the system to operate without any
external crystal and the bootloader code to operate at a known frequency.

Optional warning interrupt can be generated at a programmable time before watchdog
time-out.
Software enables the WWDT, but a hardware reset or a watchdog reset/interrupt is
required to disable the WWDT.
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) source can be selected from the IRC or the dedicated
watchdog oscillator (WDO). The clock source selection provides a wide range of
potential timing choices of watchdog operation under different power conditions.
