Bits 15 to 0: Receiver Code-Violation Counter Register (RCV[15:0]). The RCV registers form a 16-bit register
for reading the line-code violation counter value. The registers are updated with the line-code violation counter
value when the RCVUD control bit is toggled low to high. After the RCV registers are updated, the line-code
violation counter is cleared. The counter operates in two modes, depending on the setting of the ITU bit in the RCR
register. See the RCR register description for details about the ITU control bit.
