5.2 Pin Attributes

The following list describes the contents of each column in the Pin Attributes table:

1. Ball Number: Ball numbers assigned to each terminal of the Ball Grid Array package.

2. Ball Name: Ball name assigned to each terminal of the Ball Grid Array package (this name is typically taken

from the primary MUXMODE 0 signal function).

3. Signal Name: Signal name of all dedicated and pin multiplexed signal functions associated with a ball.

Note

The Pin Attributes table, defines the SoC pin multiplexed signal function implemented at the pin

and does not define secondary multiplexing of signal functions implemented in device subsystems.

Secondary multiplexing of signal functions are not described in this table. For more information on

secondary multiplexed signal functions, see the respective peripheral chapter of the device TRM.

4. Mux Mode: The MUXMODE value associated with each pin multiplexed signal function:

• MUXMODE 7 is the primary pin multiplexed signal function. However, the primary pin multiplexed signal

function is not necessarily the default pin multiplexed signal function.

• MUXMODE values 1 through 15 are possible for pin multiplexed signal functions. However, not all

MUXMODE values have been implemented. The only valid MUXMODE values are those defined as pin

multiplexed signal functions within the Pin Attributes table. Only defined valid values of MUXMODE can

be used.

• Bootstrap defines SOC configuration pins, where the logic state applied to each pin is latched on

the rising edge of PORz. These input signal functions are fixed to their respective pins and are not

programmable via MUXMODE.

• An empty box or "-" means Not Applicable.

Note

• The value found in the MUX MODE AFTER RESET column defines the default pin multiplexed

signal function selected when PORz is deasserted.

• Configuring two pins to the same pin multiplexed signal function can yield unexpected results and is

not supported. This can be prevented with proper software configuration.

• Configuring a pad to an undefined multiplexing mode results in undefined behavior and must be

avoided.

5. Type: Signal type and direction:

• I = Input

• O = Output

• ID = Input, with open-drain output function

• 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

6. Ball State During Reset (RX/TX/PULL): State of the terminal while PORz is asserted, where RX defines

the state of the input buffer, TX defines the state of the output buffer, and PULL defines the state of internal

pull resistors:

• RX (Input buffer)

– Off: The input buffer is disabled.
