5 - Reserved
The value read from these bits is always 0. Do not set these bits.
4 - NAKOUTE - NAK OUT Interrupt Enable bit
Set to enable an endpoint interrupt (EPINTx) when NAKOUTI is set.
Clear to disable an endpoint interrupt (EPINTx) when NAKOUTI is set.
3 - RXSTPE - Received SETUP Interrupt Enable flag
Set to enable an endpoint interrupt (EPINTx) when RXSTPI is sent.
Clear to disable an endpoint interrupt (EPINTx) when RXSTPI is sent.
2 - RXOUTE - Received OUT Data Interrupt Enable flag
Set to enable an endpoint interrupt (EPINTx) when RXOUTI is sent.
Clear to disable an endpoint interrupt (EPINTx) when RXOUTI is sent.
1 - STALLEDE - Stalled Interrupt Enable flag
Set to enable an endpoint interrupt (EPINTx) when STALLEDI is sent.
Clear to disable an endpoint interrupt (EPINTx) when STALLEDI is sent.
0 - TXINE - Transmitter Ready Interrupt Enable flag
Set to enable an endpoint interrupt (EPINTx) when TXINI is sent.
Clear to disable an endpoint interrupt (EPINTx) when TXINI is sent.
7-0 - DAT7:0 -Data bits
Set by the software to read/write a byte from/to the endpoint FIFO selected by EPNUM.
7-3 - Reserved
The value read from these bits is always 0. Do not set these bits.
2-0 - BYCT10:8 - Byte count (high) bits
Set by hardware. This field is the MSB of the byte count of the FIFO endpoint. The LSB part is
provided by the UEBCLX register.
