The L64704 provides the user with a mechanism to observe the output
of each functional block in the decoding pipeline. This feature simplifies
performance characterization and system diagnostics tasks.
shows the functional blocks in the decoding pipeline.
You can observe the outputs from the Descrambler, Reed-Solomon
Decoder, Viterbi Decoder, Deinterleaver Module and the QPSK Demod-
ulator through the CO[7:0], DVALIDOUT, ERROROUT, FSTARTOUT and
BCLKOUT output signals. To select an output, the external microcontrol-
ler must set the output selector bits in the OS[2:0] (Group 4, APR 12)
register to enable the appropriate functional block output. See the
description for OS[2:0] on
Channel Interfaces and Data Control
