I need a pin on the doughterboard I/f (i don't have any
doughterboard,
I just need a simple pin from I/F) for midi communication on 32000
baud (just one way communication - sending midi data - ones and zeros)
. any suggestion how to do that, which pin can I use?how? any example?
please help.
thanks in advance!

I like to use DB_CNTL0 or DB_CNTL1 for single bit control.
See schematics [page 10]. This is at the same address as the
LEDs.

How to configure the DB_CNTL0 / DB_CNTL1 as Input or
Output. Can you give documentation to refer this part.
Thank
you

Thank you for your information, Before knowing DB_CNTL0/1 I am using
McBSP as GPIO. :). So I musnt share my UART connection with GPIO
again. Btw this address is valid only for DSK6711, right ? Because
0x9xxx xxxx is connected to Flash ROM in Dsk6711 which also share
with LED and switch.
Thank you

Henrry,
Yes, this information is hardware specific. the 0x9xxxxxxx CE space
is shared by FLASH and the LED/switches. Add bit 19 is used to select
between the two.
BTW, most boards that support a daughtercard have DB_CNTL0/1 at *some*
address.
