Table 60. DC Characteristics

Note: 1. Reset (Reset) has hysteresis. VIL1 is valid at or below 0.2VCC –0.1. VIH1 is valid at or above 0.8VCC .

2. CSI deselected or internal Power-down mode is active.

3. PLD is in non-Turbo mode, and none of the inputs are switching.

4. Please see Figure 35 for the PLD current calculation.
