User manual
Table 6.
See
The LPC111x/LPC11Cxx 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 LPC111x/LPC11Cxx 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.
The SYSAHBCLKCTRL register gates the system clock to the various peripherals and
memories. UART, the WDT, and SPI0/1 have individual clock dividers to derive peripheral
clocks from the main clock.
The main clock and the clock outputs from the IRC, the system oscillator, and the
watchdog oscillator can be observed directly on the CLKOUT pin.
