Note:
1.
VDD_CON: This is a power supply pin that is used by the three control pins (VDD_SEL, CH_SEL, and OE).
In single host mode, VDD_CON should be tied to the same supply as the VDDA pin. In dual host mode,
VDD_CON should be tied to the same supply as either the VDD_HI or the VDD_LO pin, depending upon which
host is used to drive the control pins.
