Hi All,
I am sorry if the following is a stupid question but I am not sure.
On the RCM5700 module there are /RESET (pin28) and /RESET_IN (pin 16) pins. Tooking a look at the electrical scheme of the module it seems that /RESET is the output pin of the reset generator placed on the module and /RESET_IN is the input.
On my application I think to use /RESET like the reset system and let /RESET_IN pin floating.
What do you think about?
Thank you in advance.
Depends on what you’re trying to do… If you want to force a reset, pull the /RESET_IN low. If you want to know when the system has been reset (to initialize your hardware), then use /RESET.
sgt,
I want to provide a reset signal to the MCU.
So, why should I use the reset generator?
On my system I tie the /RESET signal high (using 1K resistor) and then I use
a switch to set low the line when I want a reset.
Is it?
The RCM5700 uses a MIC811 reset generator. This has active outputs and does not require a pullup resistor.
The main reason for using the reset generator is that it will give you a guaranteed minimum reset pulse width (140 ms), which will eliminate someproblems you might see with switch bounce.
Thank you for the info. I am performing some tests on this reset issue but there is something strange.
I will let you know if I found something.
Thank you.
