WR_EN=WRITE_MODE_IS_DISABL, RD_EN=READ_MODE_IS_DISABLE
USB Control
| RD_EN | Read mode control. Enables reading data from the OUT endpoint buffer for the endpoint specified in the LOG_ENDPOINT field using the USBRxData register. This bit is cleared by hardware when the last word of the current packet is read from USBRxData. 0 (READ_MODE_IS_DISABLE): Read mode is disabled. 1 (READ_MODE_IS_ENABLED): Read mode is enabled. |
| WR_EN | Write mode control. Enables writing data to the IN endpoint buffer for the endpoint specified in the LOG_ENDPOINT field using the USBTxData register. This bit is cleared by hardware when the number of bytes in USBTxLen have been sent. 0 (WRITE_MODE_IS_DISABL): Write mode is disabled. 1 (WRITE_MODE_IS_ENABLE): Write mode is enabled. |
| LOG_ENDPOINT | Logical Endpoint number. |
| RESERVED | Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined. |
