 		 #142955 - you are talking about the RC resets, I assume
Responding to: ???'s previous message
Richard Erlacher said:
Since RESET is irrelevant with a slowly decaying Vcc, and is unable to prevent unpredictable action of the MCU, these devices may not be so effective during momentary power loss, brownout, or shut-down.

This is certainly the case of RC reset.

A proper reset IC generates the appropriate output reset signal, regardless of speed of VCC decay.

                                 It\'s the power supply, and probably not the reset.            01/01/70 00:00      
                                    That's not what the bible states...            01/01/70 00:00      
                                       Isn't that the same thing with different syntax?            01/01/70 00:00      
                                          No, is not. Look at INTEL's original C51 manual!            01/01/70 00:00
