software reset & hardware reset???????

wht is software reset and hardware reset???????????

Hi,

Software reset is a reset managed by software by writting a special register bit dedicated for this purpose, it's usually a synchronous reset.

Hardware reset is the traditional reset activated by setting the IC reset pin to '1' or '0' (depending on the convention: active low or active high reset), it can be also generated inside the IC.

Hope my answer is clear!

Yours,

hardware reset is expectly applying reset signal to chip !!

software reset is -- this reset is generated by software which is sitting inside chip !

in fact hardware reset sometime is produced by software, for example mcu send the reset signal to gpio which connect some chip reset pin.

Usually software reset can't really reset the whole HW FSM which is responsible for the software execution.

But HW reset can reset the whole HW FSM (including SW FSM if any).

Sotware reset mean you will put some condition in software and based on that whole system will reset and go to starting place.

Hardware reset means you will disconnect the power for some time that required by any IC(Device) to Get reset. Normally this time is given in its mannual.

My answer is a bit from Microcontroller site, altough Hope so it will clear your confusion..:|
