5.3 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 which is implemented at the pin and selected via IOMUX pad configuration

registers. Some device subsystems provide secondary multiplexing of signal functions, which are not

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

respective peripheral chapter of the device TRM.

2. PIN TYPE: Signal direction and type:

• I = Input

• O = Output

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

• ID = Input with open-drain output function

• OD = Output, with open-drain output function

• 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

3. DESCRIPTION: Description of the signal

4. BALL: Associated ball number

For more information on the I/O cell configurations, see the Pad Configuration Registers section within the

Device Configuration chapter of the device TRM.
