I am attempting to initialize a McBSP on the '5410 to receive. I put the port into reset by writing 0h to SPCR(1,2), then write to configuration registers, wait for two clocks, enable the port by writing 1h to SPCR(1,2), then want to set bit 7 to 1 in SPCR2 to set up for internally generated frame synch. After I enable the ports, however, I cannot write correct values to SPCR2. The register value always comes out as 0003h instead of 0083h after trying to set bit 7. I am assembling and linking as follows: ASM500 mcbspini.asm LNK500 mcbspini.obj -o mcbspini.out -e entry How does one generally go about setting up for internally generated frame synch? I am following the serial port initializing procedure on page 2-24 of TMS320C54x DSP Reference Set Volume 5: Enhanced Peripherals (SPRU302). Any help would be greatly appreciated, Leigh W.
