Hello All,
There is a necessity to connect the 16 bit SPI DAC to the SPORT on the ADSP BF531 (silicon rev. 0.3). I am initializing the SPORT in the prescribed manner:
TCLKDIV = 2 TFSDIV = 31 // just in case TCR2 = 0x000F; // word length - 1 TCR1 = 0x7603; // alt. framing mode
The SPORT is supposed to work like the SPI: a write to the TX register should generate the SPI cycle. However nothing happens. The clocks are generated at all time (like it supposed to be), the TFS and data are staying inactive. The other modes of the SPORT seem to work right.
Am I doing something wrong? Or is it another bug in the silicon?
