I/O AC parameters

This section includes the AC parameters of the following I/O types:

•

General Purpose I/O (GPIO)

•

Double Data Rate I/O (DDR) for LPDDR4 and DDR4 modes

•

LVDS I/O

The GPIO and DDR I/O load circuit and output transition time waveforms are shown in Figure 7 and

Figure 8.

3.5.1

General purpose I/O AC parameters

This section presents the I/O AC parameters for GPIO in different modes. Note that the fast or slow I/O

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