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 |
