I know that. And if you read the datasheet you'll see references to the 4xPLL. You must be using an external 40Mhz clock if you're not using the internal PLL.

I will post the test code - no problem but what I can't get is WHY the pins don't toggle when I use the I2C command - they should shouldn't they?
Then post the code...
