Oscillator output
System clock output
Clock module power supply inputs
Reset signal from reset controller
This input is driven by an external clock except when used as a
connection to the external crystal when using the internal oscillator.
This output is an internal oscillator connection to the external crystal.
This output reflects the internal system clock.
