Hello,

I've set up my SPI slave device at 200kHz to receive, but can't get the interrupt to trigger at all. For debugging purposes, I've removed all timers and other interrupts. My feeling is that I may be missing something in the init.

I'm using SYSCLK / 64 as the oscillator and SPI0CKR is at 0x00 by default (which will give me the 200kHz). I've set the MISO to push-pull, and left the other 3 pins as open-drain.

Here's my code:

...
void init()
{
    SPI0CN    = 0x05;
    P0MDOUT   = 0x02;
    XBR0      = 0x02;
    XBR1      = 0xC0;
    OSCICN    = 0x81;
    IE        = 0xC0;
}

...

static void spi_isr(void) interrupt 6
{
    // doesn't come in here at all
    int q = 0;
    q++;
}

...

I appreciate if anyone can let me know what I'm missing here...Thanks!
