Yep: What a pain...
Not really explicitly said but page 9-20 and 9-25 transmit and receive
control registers. Notice there is no SDEN_B or SCHEN_B control bits as
there are in standard or I2S modes.

Also page 9-34 SCHEN and SDEN, "All operation modes for primary (A) SPORT
channels. I2S and standard modes only for secondary (B) SPORT channels.."

Hope that helps...It may be in a paragraph some ware in the book, but I cant
find it ether.

Hello all,

the 65L has two serial ports, 0 and 1. Each serial port consist of
two seperate data lines, A and B, making a total of four serial I/O
lines.

I seem to remember that when a serial port was operated in
multichannel mode, it could not operate both A and B lines
simultaneously, just one of them. However, I can't find this
information in the manual anymore. Can anybody point me to the
correct page in the "ADSP-21065L SHARC User's Manual"?

Kind regards,
Andor Bariska
