The following list describes the contents of each column in the Pin Attributes table:
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.
Configuring a pad to an undefined multiplexing mode results in undefined behavior and must be avoided.
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
PWR = Power
GND = Ground
For more information, see valid operating voltage range defined for each power supply in Recommended Operating Conditions.
For more information, see the hysteresis values in Electrical Characteristics.
Configuring two pins to the same pin multiplexed signal function is not supported as this yields unexpected results. Issues can be easily prevented with the proper software configuration.
When a pad is set into a multiplexing mode which is not defined by pin multiplexing, that pad’s behavior is undefined. This must be avoided.
For electrical characteristics, refer to the appropriate buffer type table in Electrical Characteristics.
