Figure 18. Asynchronous power-on RESET (EA = 0)
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 Figures 30,
It occurs when RSTIN is low and RPD is detected (or becomes) low as well.
Note 1. 3 to 8 TCL depending on clock source selection.
