Write:
This read/write bit enables the Transmit HUB Endpoint 0 to generate
CPU interrupt requests when the TXDF bit becomes set. Reset clears
the TXDIE bit.
This read/write bit enables the Receive HUB Endpoint 0 to generate
CPU interrupt requests when the RXDF bit becomes set. Reset clears
the RXDIE bit.
Writing a logic 1 to this write only bit will clear the TXDF bit if it is set.
Writing a logic 0 to TXDFR has no effect. Reset clears this bit.
Writing a logic 1 to this write only bit will clear the RXDF bit if it is set.
Writing a logic 0 to RXDFR has no effect. Reset clears this bit.
1 = USB interrupt enabled for Transmit HUB Endpoint 0
0 = USB interrupt disabled for Transmit HUB Endpoint 0
