I think the PLL documentation would benefit from a re-write ...

My understanding is as follows:

Cclk (the CPU clock) will be M (an integer value, 1-6) * FOSC

Cclk must lie between 10 MHz and 60 MHz

Fcco will be M * FOSC * 2 * P (an integer value, 2,4,8 or 16)

Fcco must be between 156 MHz and 320 MHz


Am I correct?

If so, can someone explain to me why P is referred to in the documentation
as a divider?


Thanks,

Michael.
