GPIO Test code using SPI

Hi,

I am using ADS1298 with Freescale MC 1322x. I am stuck with the initial configuration of the ADS1298.

Before going into acquiring the signal, I wanted to test by toggling the GPIO signals.

Before going into acquiring the signal, I wanted to test by toggling the GPIO signals.

So here is what I have written.

0x02; wake up

0x12; RDATAC to RREG

for(;;)
{
0x5400; Select 0x14h i.e GPIO register and write data to it
0x01; GPIO 1 set 0
delay(1000ms)

0x5400;
0x11; GPIO 1 set 1
delay (1000ms)
}

I am not able to get any signals on GPIO.
I have also taken care of clock polarity and phase. 
Please help me out with this.
