5. Pin Description

Most pins can be configured for multiple functions, analog or digital. Digital inputs can be connected to multiple peripherals at once, but only one digital output or Analog functions can be assigned to any pin. The connection of pins to internal peripheral modules is configured by switch matrix (SWM), input multiplexer (INPUT MUX), and SCT input preprocessing unit (SCTIPU). The switch matrix enables certain fixed pin functions that can only reside on specific pins, and assigns all other pin functions (movable functions) to any available pin for a given application. The input multiplexer provides several options (pins and internal signals) for selecting the inputs to the SCTimer/PWM and frequency measurement modules. Table 5 lists the pins connected to the input multiplexer. If a pin is selected in the input multiplexer, it is connected directly to the peripheral input without routing through the switch matrix. Independent of being selected in the input multiplexer, the same pins can also Assigned to another peripheral input by the switch matrix. These four pins can also be connected directly to the SCTIPU as inputs to the input multiplexer and switch matrix.
