| EP3_TX_MAX_P_REG | 0x0130 | 16 | RW | 0 | Maximum packet size for host transmit endpoint3. |
| EP3_TX_CSR_REG | 0x0132 | 16 | R | 0 | Provides control and status bits for transmit endpoint3. |
| EP3_RX_MAX_P_REG | 0x0134 | 16 | RW | 0 | Defines the maximum amount of data that can be transferred through receive endpoint3 in a single operation. |
| EP3_RX_CSR_REG | 0x0136 | 16 | R | 0 | Provides control and status bits for transfers through the receive endpoint3. |
| EP3_RX_COUNT_REG | 0x0138 | 16 | R | 0 | Holds the number of data bytes in the packet currently in line to be read from the endpoint3 receive FIFO. If the packet is transmitted as multiple bulk packets, the number given will be for the combined packet. |
| EP3_TX_TYPE_REG | 0x013A | 8 | W | 0 | Reads the number of bytes from peripheral endpoint3 transmit FIFO. |
| EP3_TX_INTERVAL_REG | 0x013B | 8 | RW | 0 | Sets the polling interval for interrupt/ISOC transactions or the NAK response timeout on bulk transactions for host transmit endpoint3. |
| EP3_RX_TYPE_REG | 0x013C | 8 | RW | 0 | Sets the transaction protocol, speed, and peripheral endpoint number for the host receive endpoint3. |
| EP3_RX_INTERVAL_REG | 0x013D | 8 | RW | 0 | Sets the polling interval for interrupt/ISOC transactions or the NAK response timeout on bulk transactions for host receive endpoint3. |
| EP3_FIFO_SIZE_REG | 0x013E | 8 | R | — | Returns the configured size of the endpoint3 receive FIFO and transmit FIFOs. |
