AFAIK, the FRC option (8MHz internal) doesn't work with PLL.
PLL can be applied only to the primary oscillator

So, maybe you can assume that the 3012 is running at 8MHz. You'd
think that would be the fastest simplest configuration. If so, then you
could work out what the highest SPI rate would be. Don't uM give
any information like that ? What speed do you get up to before the
SPI fails ?
