7.15 Clocking and power control
The LPC1111/12/13/14 include three independent oscillators. These are 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 LPC1111/12/13/14 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
The IRC may be used as the clock source for the WDT, and/or as the clock that drives the
PLL and subsequently the CPU. The nominal IRC frequency is 12 MHz. The IRC is
trimmed to 1 % accuracy over the entire voltage and temperature range.
