[hpsdr] FXLP GPIF page chaining?

[Jim Miller]

I was trying to do a simple version of an FX2LP AutoIn/AutoOut using the 
GPIF machines to continuously stream audio bytes in/out from the endpoints 
without 8051 intervention. The reads and writes would need to interleave 
after being triggered.

Doesn't seem possible after several readings of the TRM...

Otherwise it seems it requires the '51 to trigger a fifo in for a few 
transactions (bytes) then immediately trigger a fifo out for a few 
transactions. The transaction counter would be used in S7 to determine 
whether to quit and allow the other fifo transaction burst to occur. The 
burst length would need to be sized long enough to keep from running the '51 
ragged setting up the next transaction.

Any ideas?
