SW1 to SW4 inputs to the AT91 are not valid. This authorizes users to
connect the corresponding PIO to their own resources via the I/O Expansion
Connector.
AT91 Master Clock Input
AT91 Master Clock input (MCKI) is connected to the on-board 66 MHz
oscillator.
AT91 Master Clock input (MCKI) is connected to the EBI_MCKI (B4) pin of
the EBI expansion connector. This authorizes the user to input an external
clock to the AT91.
