LPC122x
32-bit ARM Cortex-M0 microcontroller
Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 224 4) in
multiples of Tcy(WDCLK) 4.
The Watchdog Clock (WDCLK) source can be selected from the Internal RC oscillator
(IRC) or the Watchdog oscillator. This gives a wide range of potential timing choices of
Watchdog operation under different power reduction conditions. It also provides the
ability to run the WDT from an entirely internal source that is not dependent on an
external crystal and its associated components and wiring for increased reliability.
7.17 Real-time clock (RTC)
The RTC provides a basic alarm function or can be used as a long time base counter. The
RTC generates an interrupt after counting for a programmed number of cycles of the RTC
clock input.
7.17.1 Features
Uses dedicated 32 kHz ultra low-power oscillator.
Selectable clock inputs: RTC oscillator (1 Hz, delayed 1 Hz, or 1 kHz clock) or main
clock with programmable clock divider.
32-bit counter.
Programmable 32-bit match/compare register.
Software maskable interrupt when counter and compare registers are identical.
Generates wake-up from Deep-sleep and Deep power-down modes.
7.18 Clocking and power control
7.18.1 Crystal oscillators
The LPC122x include four independent oscillators. These are the system oscillator, the
Internal RC oscillator (IRC), the RTC 32 kHz oscillator (for the RTC only), and the
Watchdog oscillator. Except for the RTC oscillator, each oscillator can be used for more
than one purpose as required in a particular application.
Following reset, the LPC122x will operate from the Internal RC oscillator until switched by
software. This allows systems to operate without any external crystal and the bootloader
code to operate at a known frequency.
See Figure 5 for an overview of the LPC122x clock generation.
