Re: [avr-gcc-list] Watchdog Reset

[Ian Caddy]

Hi,

Well, there are two levels here.

At the hardware level, the watchdog reset will not effect the RAM, but 
if you are coding in C, after the reset, the C initialisation code will 
clear the RAM for the unitialised data, and set the initialised data to 
the correct initial values.

If you use a RAM location that is outside your C memory map, it should 
not be effected by a watchdog reset.

I hope this helps,

Ian Caddy
