Endpoint X FIFO data
Data byte to be written to FIFO or data byte to be read from the FIFO, for the
Endpoint X (see EPNUM).
Byte Count LSB
Least Significant Byte of the byte count of a received data packet. The most
significant part is provided by the UBYCTHX Register UBYCTHX (S:E3h) USB
Byte Count High Register X (X = EPNUM set in UEPNUM Register UEPNUM
(S:C7h) USB Endpoint Number) (see Figure 100 on page 142). This byte count is
equal to the number of data bytes received after the Data PID.
