(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) IO drive strength for usb1_dp, usb1_dm, usb2_dp and usb2_dm: minimum 18.3 mA, maximum 89 mA (for a power supply vdda33v_usb1 and vdda33v_usb2 = 3.46 V).
(6) Minimum PU = 900 Ω, maximum PU = 3.090 kΩ and minimum PD = 14.25 kΩ, maximum PD = 24.8 kΩ.
For more information, see chapter 7 of the USB2.0 specification, in particular section Signaling / Device Speed Identification.
(7) This function will not be supported on some pin-compatible roadmap devices. Pin compatibility can be maintained in the future by not using these GPIO signals.
(8) In PUx / PDy, x and y = 60 to 200 μA.
The output impedance settings (or drive strengths) of this IO are programmable (34 Ω, 40 Ω, 48 Ω, 60 Ω, 80 Ω) depending on the values of the I[2:0] registers.
4.3 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.
