synchronizing the MsBSP ports

I’m using a dsk6711 to implement a delta sigma modulator. I need to write to both McBSP0 and McBSP1 synchronously. What is the easiest way to implement this?

I am useing the following routine to initialize the McBSP ports but it seems that usually McBSP0 starts one clock cycle sooner than McBSP1 (I mean the FSX0 is one bit ahead of FSX1). However it seems it is random and as I reset the CPU and reload it again, the situation might change and the ports might become synchronized.

Thanks,

Mohammad

void McBSPInit(void)

{

Uint32 Temp=0,Data=0;

    MCBSP_enableSrgr(hMcbsp1);     // Enable the sample rate generator  

    MCBSP_enableSrgr(hMcbsp0);     // Enable the sample rate generator

    for (Temp=0;Temp<150;Temp++) //Should have a two clock cycle delay here

        Data++;

   init_HWI();      // Enabling Interrupts

    MCBSP_enableXmt(hMcbsp0);     // Enable the transmitter0  

    MCBSP_enableRcv(hMcbsp0);   // Enable the receiver0

    MCBSP_enableXmt(hMcbsp1);     // Enable the transmitter1  

    MCBSP_enableRcv(hMcbsp1);      // Enable the receiver1

    MCBSP_enableFsync(hMcbsp0);   // Enable the frame sync generator0  

    MCBSP_enableFsync(hMcbsp1);   // Enable the frame sync generator1 

    MCBSP_write(hMcbsp0, 0xF0F0);

    MCBSP_write(hMcbsp1, 0xF0F0);

}
