7.2 Pin description

Most pins are configurable for multiple functions, which can be analog or digital. Digital

inputs can be connected to several peripherals at once, however only one digital output or

one analog function can be assigned to any on pin. The pin’s connections to internal

peripheral blocks are configured by the switch matrix (SWM), the input multiplexer (INPUT

MUX), and the SCT Input Pre-processor Unit (SCTIPU).

The switch matrix enables certain fixed-pin functions that can only reside on specific pins

(see Table 3) and assigns all other pin functions (movable functions) to any available pin

(see Table 4), so that the pinout can be optimized for a given application.

The input mux provides many choices (pins and internal signals) for selecting the inputs of

the SCTimer/PWMs and the frequency measure block. Pins that are connected to the

input mux are listed in Table 5. If a pin is selected in the input mux, it is directly connected

to the peripheral input without being routed through the switch matrix. Independently of

being selected in the input mux, the same pin can also be assigned by the switch matrix to

another peripheral input.

Four pins can also be connected directly to the SCTIPU and at the same time be inputs to

the input mux and the switch matrix (see Table 5).
