Reset sequence — start condition

The impact of the voltage thresholds on the starting point of the internal reset sequence are

becoming important if the voltage rails / signals ramp up with a very slow slew rate

compared to the overall reset sequence duration.

Destructive reset

Figure 17 shows the voltage threshold that determines the start of the Destructive Reset

Sequence, BIST enabled and the start for the Destructive Reset Sequence, BIST disabled.

Figure 17. Reset sequence start for Destructive Resets

External reset via RESET

Figure 18 shows the voltage thresholds that determine the start of the reset sequences

initiated by the assertion of RESET as specified in Table 31.

If RESET is configured for short reset

Internal reset sequence can only be observed by state of RESET if bidirectional RESET functionality is enabled for the

functional reset source which triggered the reset sequence.
