status RAM at the address on the csram_addr port.
If each input audio pair gets separate channel status RAMs,
this signal addresses the RAM selected by the
extended_control port.
csram_data
[7:0]
Input
Channel status data. This signal does the same function as
the channel status RAM register in Table 4–9 .
Table 4–7 lists the register interface signals. The register interface is a standard 8-bit
wide Avalon-MM slave.
