The oscillators are not mapped to the normal GPIO functions and their muxings are controlled
by registers in the System Control Interface (SCIF). Please refer to the SCIF chapter for more
information about this.
The functions listed in
pin will only be active after the aWire is enabled. The aWire DATAOUT pin will only be active
after the aWire is enabled and the 2_PIN_MODE command has been sent. The WAKE_N pin is
always enabled. Please refer to
