TXDIE — Hub Endpoint 0 Transmit Interrupt Enable
This read/write bit enables the TXDF bit to generate CPU interrupt
request when set. Reset clears the TXDIE bit.
1 = TXDF CPU interrupt requests enabled
0 = TXDF CPU interrupt requests disabled
RXDIE — Hub Endpoint 0 Receive Interrupt Enable
This read/write bit enables the RXDF bit to generate CPU interrupt
request when set. Reset clears the RXDIE bit.
1 = RXDF CPU interrupt requests enabled
0 = RXDF CPU interrupt requests disabled
TXDFR — Hub Endpoint 0 Transmit Flag Reset
Writing a logic 1 to this write-only bit will clear the TXDF bit if it is set.
Reset clears this bit.
1 = Write 1 to clear the TXDF bit
0 = No effect
RXDFR — Hub Endpoint 0 Receive Flag Reset
Writing a logic 1 to this write-only bit will clear the RXDF bit if it is set.
Reset clears this bit.
1 = Write 1 to clear the RXDF bit
0 = No effect
