CP2400/1/2/3
5.
CP2400/1/2/3 devices include a 20 MHz internal oscillator that is selected as the system clock source upon reset.
Additional clocking options include an external CMOS clock input, the internal oscillator divided by 2, 4, or 8, and
the SmaRTClock real time clock oscillator. The system clock source is selected using the CLKSEL register. The
system clock selection may always be overridden by an external CMOS clock if the CLKOVR bit (MSCN.2) is set.
