18.5.39 USB Receive Byte Count Endpoint n Registers (USBRXCOUNT[1]-USBRXCOUNT[15])

The USB receive byte count endpoint n 16-bit read-only registers hold the number of data bytes in the
packet currently in line to be read from the receive FIFO. If the packet is transmitted as multiple bulk
packets, the number given is for the combined packet.
Note: The value returned changes as the FIFO is unloaded and is only valid while the RXRDY bit in the
USBRXCSRLn register is set.
