13.2 Crystal oscillator
The crystal oscillator is controlled by the XTAL_OSC_CTRL register in the CGU (see
LPC18xx user manual).
The crystal oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be
boosted to a higher frequency, up to the maximum CPU operating frequency, by the PLL.
The oscillator can operate in one of two modes: slave mode and oscillation mode.
