The embedded MPU generates the necessary clocks based on two oscillators: one slow clock (SLCK) crystal running at 32.768 kHz and one main clock oscillator running at 12 MHz. An optional 12 MHz crystal is available as an alternative to the DSC1001DL5-012.0000 oscillator.
Note: PIOBU0 can be used to disable the 12 MHz main oscillator (Y3).
