6.2 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(s) 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 0 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 valid values of MUXMODE should be

used.

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

rising edge of PORz_OUT. 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 MCU_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 will result in undefined behavior and

should be avoided.
