Note: Because there are at most two choices of alternate function for some pins of Port A, the Alternate Function Set
register AFS2 is implemented but not used to select the function. Also, alternate function selection as described

For systems using an external TTL drive, PB3 is the clock source for 20-pin, 28-pin, 
40-pin, and 44-pin devices. In this case, configure PB3 for alternate function CLKIN.
Write the Oscillator Control Register (see page 308) such that the external oscillator is
selected as the system clock.
