Not Assigned. Could be any value when read.
Receive All Ones. Set when 32 consecutive 1s are received; allowed to be
cleared when a 0 is received.
Receive All Zeros. Set when 32 consecutive 0s are received; allowed to be
cleared when a 1 is received.
Receive Loss Of Sync. Set when the device is searching for
synchronization. Once sync is achieved, will remain set until read.
Bit Error Detection. Set when bit errors are detected.
Bit Counter Overflow. Set when the 32-bit BCR overflows.
Bit Error Count Overflow. Set when the 32-bit BECR overflows.
Sync. Real time status of the synchronizer (this bit is not latched). Will be
set when synchronization is declared. Will be cleared when 6 or more bits
out of 64 are received in error (if PCR.2 = 0).
