12.10 First 48 Channel Status Bits Update Flag Output (CSFLAG)
CSFLAG compares the first 48 bits of channel status data of the previous block with those of the current block and
outputs low in case they are the same, and high in case they are different, for 1 block of 192 frames. Therefore the
channel status data output after the falling edge of the CSFLAG is the latest data.
CSFLAG outputs high regardless of the comparison result until ERROR outputs low. After ERROR output becomes
low, CSFLAG outputs low after the first 48bit data of the previous data and the current data have been confirmed to
be identical.

CSFLAG pin
Output condition
L
Previous data current data are identical
H
Previous data differs from current data

12.11 Non-PCM Burst Preamble Detection Signal Output (BPSYNC)
BPSYNC outputs low while Non-PCM burst preamble Pa, Pb, Pc and Pd output, when Pa and Pb are detected
following continuous all zero data of two frame. However, when output data delay is set up, low period of a BPSYNC
signal and the output period of the Non-PCM burst preamble Pa, Pb, Pc, and Pd do not match. In this case, BPSYNC
is output ahead of Pa, Pb, Pc, and Pd data.
Pa, Pb, Pc and Pd are detected from the receive data even when an input parity error occurs.
