Charge Pump Interface
VBUS for the USB OTG port can be produced by EZ-Host using
its built in charge pump and some external components. Ensure
the circuit connections look similar to the following diagram.

If the VBUS charge pump circuit is not to be used, CSWITCHA,
CSWITCHB, and OTGVBUS can be left unconnected.

CY7C67300
D1 and D2: Schottky diodes with a current rating greater than
60 mA
C1: Ceramic capacitor with a capacitance of 0.1 µF
C2: Make capacitor value no more that 6.5 µF since that is the
maximum capacitance allowed by the USB OTG specifications
for a dual role device. The minimum value of C2 is 1 µF. There
are no restrictions on the type of capacitor for C2.
