6.3 Signal Descriptions

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 PADCONFIG

registers. Device subsystems may 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

• 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

• PWR = Power

• GND = Ground

• CAP = LDO Capacitor

3. DESCRIPTION: Description of the signal

4. BALL: Ball number(s) associated with signal

For more information on the IO cell configurations, see the Pad Configuration Registers section in Device

Configuration chapter of the device TRM.
