6.3 Signal Descriptions

Many signals are available on multiple pins, according to the software configuration of the pin multiplexing

options.

The following list describes the column headers:

1. Signal Name: The name of the signal passing through the pin.

Note

Signal names and descriptions provided in each Signal Descriptions table, represent the pin

multiplexed signal function implemented at the pin and selected via PADCONFIG registers. Some

device subsystems provide an additional layer of multiplexing for signal functions that are not

described in these tables. For more information on secondary multiplexed signal functions, see

the respective peripheral chapter of the device TRM.

2. Signal Type: Signal type and direction:

• I = Input

• O = Output

• OD = Output, with open-drain output function

• IO = Input, Output, or simultaneously Input and Output

• IOD = Input, Output, or simultaneously Input and Output, with open-drain output function

• IOZ = Input, Output, or simultaneously Input and Output, with three-state output function

• OZ = Output with three-state output function

• A = Analog

• CAP = LDO capacitor

• PWR = Power

• GND = Ground
