Pin Multiplexing Control

Device level pin multiplexing is controlled by registers PINMUX0 - PINMUX19 in the SYSCFG module.

For the device family, pin multiplexing can be controlled on a pin-by-pin basis. Each pin that is multiplexed

with several different functions has a corresponding 4-bit field in one of the PINMUX registers.

Pin multiplexing selects which of several peripheral pin functions controls the pin's IO buffer output data

and output enable values only. The default pin multiplexing control for almost every pin is to select 'none'

of the peripheral functions in which case the pin's IO buffer is held tri-stated.

Note that the input from each pin is always routed to all of the peripherals that share the pin; the PINMUX

registers have no effect on input from a pin.
