Asynchronous power-on RESET (EA = 0)

1. 3 to 8 TCL depending on clock source selection.

Hardware reset

The asynchronous reset must be used to recover from catastrophic situations of the

application. It may be triggered by the hardware of the application. Internal hardware logic

and application circuitry are described in Reset circuitry chapter and Figure 37, Figure 38

and Figure 39. It occurs when RSTIN is low and RPD is detected (or becomes) low as well.
