3.9.4.14 B1 Monitor
In both modes, the HDMP-3001
checks the received B1 bytes for
correct Bit Interleaved Parity 8
(BIP-8) values. Even parity BIP-8
is calculated over all bytes of each
frame before descrambling. This
value is then compared to the re-
ceived B1 value in the following
frame after descrambling. The
comparison can result in 0 to 8
mismatches (B1 bit errors).
The HDMP-3001 contains a 16-bit
B1 error counter that counts ev-
ery B1 bit error. When the
performance monitoring counters
are latched (LATCH_EVENT tran-
sitions high), the value of this
counter is latched to the
B1_ERRCNT[15:0] register, and
the B1 error counter is cleared.
