The EPEC Block diagram is shown in Figure 20 below.
Figure 20
The TX_REQn and RX_REQn shown in Figure 20 will be generated by the USBD to
request a word transfer over the XBUS from/to the FIFOs.
Besides the transfer request interrupts the EPEC provides a 10-bit transmit counter
register per channel, which will be written by SW. After the terminal count value is
reached, the counter stops and generates and TX_DONE pulse to the USBD. For each
endpoint an EPEC_CTRL register is provided to control the endpoint.
