Description
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).
Description
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 21-11 on page 145). This byte count is equal to the number of data
bytes received after the Data PID.
