Application of single-chip microcomputer watchdog

Defined:

SFR wdt_contr=0xe1;

void Main ()

{

wdt_contr=0x34;

while (XXX)

{

wdt_contr=0x34;

}

}

Shaped like this form.

Note: in the microcontroller program design, each feeding dog operation should be carried out before the watchdog timer overflow, so that when the program is running normally, the watchdog timer can always be cleared in time, so that the watchdog does not output a forced reset signal due to the timer overflow, which is required for continuous normal operation of the program.
