SPORT Hang on 21065L - ryanhalter - Jun 23 15:31:00 2003



I am using the ADSP21065L chip and right now just implementing a
simple sport transfer between a PC serial port and the DSP chip on a
custom board(with a RS-232 Transceiver). I am sending a 32 bit
value to the DSP chip and echoing it back to the PC. What seems to
happen after a while is that the DSP SPORT receive interrupt no
longer gets yanked. I have tried to RESET the sport by setting the
control regisiter to 0x00 and then setting it to it's working value,
but the DSP chip still does not respond to a transmission of a
serial word. If I halt the process and check the IMASK regsiter the
correct sport receive interrupt is enabled.

Any ideas why my SPORT might be hanging??

thanks much

ryan
