LPC122x
32-bit ARM Cortex-M0 microcontroller
7.18.1.1
Internal RC oscillator
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.
Upon power-up or any chip reset, the LPC122x use the IRC as the clock source. Software
may later switch to one of the other available clock sources.
7.18.1.2
System oscillator
The system oscillator can be used as the clock source for the CPU, with or without using
the PLL.
