Following reset, the LPC1110/11/12/13/14/15 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.
Upon power-up or any chip reset, the LPC1110/11/12/13/14/15 use the IRC as the clock
source. Software may later switch to one of the other available clock sources.
The system oscillator can be used as the clock source for the CPU, with or without using
the PLL.
