LPC11U1x
32-bit ARM Cortex-M0 microcontroller
7.13.1.1
Internal RC oscillator
The IRC may be used as the clock source for the WDT, and/or as the clock that drives the
system PLL and subsequently the CPU. The nominal IRC frequency is 12 MHz.
Upon power-up, any chip reset, or wake-up from Deep power-down mode, the LPC11U1x
use the IRC as the clock source. Software may later switch to one of the other available
clock sources.
