UDC Byte Count Register 4

The Byte-Count Register maintains the remaining byte count in the active buffer of out
Endpoint 4.

Endpoint 4 Byte Count (BC[7:0])

The byte count is updated after each byte is read. When software receives an interrupt
that indicates the endpoint has data, it can read the byte count register to determine
the number of bytes that remain to be read.
The number of bytes that remain in the input buffer is equal to the byte count +1.
