Oscillator Clock: This clock signal is used for the 8254 timers. It runs at
14.31818 MHz. This clock is permitted to stop during S3 (or lower)
states.
48 MHz Clock: This clock signal is used to run the USB controller. It runs
at 48.000 MHz. This clock is permitted to stop during S3 (or lower)
states.
100 MHz Differential Clock: These signals are used to run the SATA
controller at 100 MHz. This clock is permitted to stop during S3/S4/S5
states.
100 MHz Differential Clock: These signals are used to run the Direct
Media Interface. They run at 100 MHz.
Crystal Input 1: This signal is connected to the 32.768 kHz crystal. If
no external crystal is used, RTCX1 can be driven with the desired clock
rate.
Crystal Input 2: This signal is connected to the 32.768 kHz crystal. If
no external crystal is used, RTCX2 should be left floating.
