|Switch matrix (SWM)|
A pin is identified for the purpose of programming the switch matrix by its default GPIO port pin number.
Example: Connect function U0_RXD and U0_TXD to pins 10 and 14 on the SO20 package
The switch matrix connects all internal signals listed in the table of movable functions through the pin assignment registers to external pins on the package. External pins are identified by their default GPIO pin number PIO0_n. Follow these steps to connect an internal signal FUNC to an external pin. An example of a movable function is the UART transmit signal TXD:
FUNC is now connected to pin x on the package.
