SPI clock

Hi,

I use CCS 6.0.1, DSP/BIOS 5.42.1.09, processor OMAP-L138 (DSP only), C6748 BIOS PSP 01.30.01.

Why it is not possible to establish an value spiParams.outputClkFreq less rather than 590000 Hz? That is there is no generation of a clock signal.

Spi_init();

spiParams = Spi_PARAMS;

spiParams.hwiNumber = 8;
spiParams.spiHWCfgData.intrLevel = FALSE;
spiParams.opMode = Spi_OpMode_INTERRUPT;

spiParams.outputClkFreq = 500000;
spiParams.loopbackEnabled = FALSE;
spiParams.edmaHandle = NULL;

spiParams.spiHWCfgData.pinOpModes = Spi_PinOpMode_SPISCS_4PIN;
spiParams.spiHWCfgData.configDatafmt[0].charLength = 8;
spiParams.spiHWCfgData.configDatafmt[0].clkHigh = TRUE; 
spiParams.spiHWCfgData.configDatafmt[0].lsbFirst = FALSE;
spiParams.spiHWCfgData.configDatafmt[0].oddParity = FALSE;
spiParams.spiHWCfgData.configDatafmt[0].parityEnable = FALSE ;
spiParams.spiHWCfgData.configDatafmt[0].phaseIn = FALSE; 

spiParams.spiHWCfgData.intrLevel = TRUE;

spiParams.spiHWCfgData.csDefault = 0xFF; 

Best regards,

Oleh
