Bits 7 to 0: Receiver Code-Violation Counter Register (RCV[7:0]). The full 16-bit RCV[15:0] field spans this
register and RCVHn. RCV is an unsigned integer that indicates the line-code violation counter value. RCV is
updated with the line-code violation counter value when the RCVUD control bit in the
high. After the RCV register is updated, the line-code violation counter is cleared. The counter operates in two
modes, depending on the setting of the ITU bit in the
about the ITU control bit.
