hi,

iam trying to interface str912 to ADC7490 using SSP.

which one we can use as a master/slave either adc/controller.

my SSP configuration seems like

SSP0->CR0 = 0x0487; //Serial CLK Rate(SCR) 4,Motorola,SCLK held low,second clock edge,8bit data

SSP0->PR = 12; //prescalar value.

SSP0->CR1 = 0x02; //SSP0 enable,Master Mode Enabled

When and how i could Enable NSS(CS) signal from LOW to HIGH,after 16 bits of data.

can anyone plz help me out

thankx in advance

regards

Madhu
