Description

Endpoint NAK (device mode)

Fields

EPRN0	Rx endpoint NAK Each RX endpoint has one 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. Bit 3 corresponds to endpoint 3. … Bit 1 corresponds to endpoint 1. Bit 0 corresponds to endpoint 0.
EPRN1	Rx endpoint NAK Each RX endpoint has one 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. Bit 3 corresponds to endpoint 3. … Bit 1 corresponds to endpoint 1. Bit 0 corresponds to endpoint 0.
EPRN2	Rx endpoint NAK Each RX endpoint has one 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. Bit 3 corresponds to endpoint 3. … Bit 1 corresponds to endpoint 1. Bit 0 corresponds to endpoint 0.
EPRN3	Rx endpoint NAK Each RX endpoint has one 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. Bit 3 corresponds to endpoint 3. … Bit 1 corresponds to endpoint 1. Bit 0 corresponds to endpoint 0.
RESERVED	Reserved
EPTN16	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. Bit 3 corresponds to endpoint 3. … Bit 1 corresponds to endpoint 1. Bit 0 corresponds to endpoint 0.
EPTN17	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. Bit 3 corresponds to endpoint 3. … Bit 1 corresponds to endpoint 1. Bit 0 corresponds to endpoint 0.
EPTN18	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. Bit 3 corresponds to endpoint 3. … Bit 1 corresponds to endpoint 1. Bit 0 corresponds to endpoint 0.
EPTN19	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. Bit 3 corresponds to endpoint 3. … Bit 1 corresponds to endpoint 1. Bit 0 corresponds to endpoint 0.
