TX Endpoint NAK.
Each TX endpoint has one bit in this field. The bit is set when the device sends a NAK handshake on a
received IN token for the corresponding endpoint.
EPTN[7] = Endpoint 7
EPTN[6] = Endpoint 6
EPTN[5] = Endpoint 5
EPTN[4] = Endpoint 4
EPTN[3] = Endpoint 3
EPTN[2] = Endpoint 2
EPTN[1] = Endpoint 1
EPTN[0] = Endpoint 0
Reserved.
RX Endpoint NAK.
Each RX endpoint has 1 bit in this field. The bit is set when the device sends a NAK handshake on a received
OUT or PING token for the corresponding endpoint.
EPRN[7] = Endpoint 7
EPRN[6] = Endpoint 6
EPRN[5] = Endpoint 5
EPRN[4] = Endpoint 4
