We are having issues seeing data on the SPI_D[0] port on a TMS320C6A8167 and have checked everything that we think might be the problem. We are seeing clock out the SPI clock pin, but no data. We noticed there is a register in the data sheet called MCSPI_HL_SYSCONFIG, but there is no mention of it in the TRM. Could this register have something in it that would be the problem? Here's a dump of my MCSPI registers:
