(1) NA in this table stands for Not Applicable.

(2) For more information on recommended operating conditions, see Table 5-4, Recommended Operating Conditions.

(3) The pullup or pulldown block strength is equal to: minimum = 50 μA, typical = 100 μA, maximum = 250 μA.

(4) The output impedance settings of this IO cell are programmable; by default, the value is DS[1:0] = 10, this means 40

Ω. For more information on DS[1:0] register configuration, see the

Device TRM.

(5) In PUx / PDy, x and y = 60 to 300 μA.

The output impedance settings (or drive strengths) of this IO are programmable (60 Ω, 80 Ω, 120 Ω) depending on the values of the I[2:0] registers.

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 Configuration Registers 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 IO timings provided in Section 7, Timing Requirements and Switching Characteristics are only valid if signals within

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