If you run an avr at 12MHz, use 8pins on PINB, you can log data to ram at 4MHz.
at 10MHz, [3+(1/3)]MHz

Thats 5MIPS (million instructions per second). PICs have a 1/4th ratio
between clock rate and instruction rate.
AVRs are 1/1 (a 12MHz avr gets 12MIPS).
There is a scenix, and it isn't totally PIC compatible. When running the
Scenix in PIC mode it has to use the 1/4 rule. When running in Scenix mode
it gets 1/1.
