Figure 5-15. DIO Timing Diagram 5.17.6.3.1 DIO Output Transition Time Parameters (Vsupply = 3.3 V) Table 5-20 lists the DIO output transition times for Vsupply = 3.3 V. (1) Vsupply = 3.3 V, T = 25°C, total pin load = 30 pF (2) The 2-mA and 4-mA drive strength does not apply to the COEX I/O pins. Pins configured as COEX lines are invariably driven at 6 mA.
