Also: peripheral muxing, interrupts in input mode, connecting a timer as PWM output to a pin (which is basically what blink is probably doing). In input mode it might also have schmitt triggering. Where's the blink getting the timer from? What happens if I update the main PLLs? I'll refrain from making assumptions however until I can see their driver libraries. I'm hopeful, but having played around with the 1830 it's not a simple chip.
