Alternate Pin Functions
1. Pin mapping of all TC0 can optionally be moved to high nibble of port.
2. Pin mapping of all USART0 can optionally be moved to high nibble of port.
3. Pins MOSI and SCK for all SPI can optionally be swapped.
4. CLKOUT can optionally be moved between pin 4 and 7.
5. EVOUT can optionally be moved between pin 4 and 7.

The tables below show the primary/default function for each pin on a port in the first column, the
pin number in the second column, and then all alternate pin functions in the remaining columns.
The head row shows what peripheral that enable and use the alternate pin functions.
For better flexibility, some alternate functions also have selectable pin locations for their func-
tions, this is noted under the the first table where this apply.
