detector. See Table 6-H for the expected PRBS pattern.
0 = in sync with expected pattern
1 = out of sync, expected pattern not detected

recovery PLL.
0 = the receiver PLL is locked onto the incoming signal
1 = the receiver PLL is not locked onto the incoming signal
Bit 0: Receiver Loss of Signal (RLOS). This read-only status bit indicates the current state of the receiver loss-of-
