20.9.2.1.14 USB0 Tx Mode Register (USB0TXMODE)

The USB0 Tx mode register (USB0TXMODE) register allows the CPU to individually enable
RNDIS/Generic/CDC modes for each endpoint. Using the global RNDIS enable in the Control Register
overrides this register and enable RNDIS mode for all endpoints.
The USB0 Tx mode register is shown in
