Multiplexing Characteristics

Table 4-3 describes the device multiplexing (no characteristics are available in this table).

NOTE

This table doesn't take into account subsystem multiplexing signals. Subsystem multiplexing signals are described in Section 4.4, Signal

Descriptions.

NOTE

For more information, see the Control Module / Control Module Functional Description / PAD Functional Multiplexing and Configuration

section of the Device TRM.

NOTE

Configuring two pins to the same input signal is not supported as it can yield unexpected results. This can be easily prevented with the

proper software configuration (Hi-Z mode is not an input signal).

NOTE

When a pad is set into a multiplexing mode which is not defined by pin multiplexing, that pad’s behavior is undefined. This should be

avoided.

CAUTION

The I/O timings provided in Section 7 Timing Requirements and Switching Characteristics are valid only if signals within

a single IOSET are used. The IOSETs are defined in the corresponding tables.
