4.3.2.1

General purpose I/O AC parameters

The I/O AC parameters for GPIO are presented in the Table 21, respectively. Note that the fast or slow I/O

behavior is determined by the appropriate control bits in the IOMUXC control registers.

1 Overshoot and undershoot conditions (transitions above NVCC_XXXX and below GND) on switching pads must be held

below 0.6 V, and the duration of the overshoot/undershoot must not exceed 10% of the system clock cycle. Overshoot/

undershoot must be controlled through printed circuit board layout, transmission line impedance matching, signal line

termination, or other methods. Non-compliance to this specification may affect device reliability or cause permanent damage

to the device.

2 To maintain a valid level, the transition edge of the input must sustain a constant slew rate (monotonic) from the current DC

level through to the target DC level, Vil or Vih. Monotonic input transition time is from 0.1 ns to 1 s.

3 Hysteresis of 250 mV is guaranteed over all operating conditions when hysteresis is enabled.
