ENDPOINT DESCRIPTIONS
There are two endpoint configuration modes supported by the PDIUSBH12, the Single Embedded Function mode and the Multiple (3)
Embedded Function mode. The Single Embedded Function mode is the default at power up reset. The Multiple (3) Embedded Function mode
can be configured by writing a zero to bit 7 of the first byte of the Set Mode command. Either mode is backward compatible to the PDIUSBH11.
