data. This maintains the previous switch state, for example, when a RESET occurs due
to an EMI problem. If, when checked, the RAM registers are not as expected, a
complete initialization procedure is launched. If the RAM area is adequate, then a
“smart reset” can be performed. Only the registers which are used to store internal sub-
routine variables are cleared, and only the main registers keep their previous values
(AC switch status, AC switch control, etc)
Use the watchdog properly. Enable the watchdog as soon as possible after reset and
never refresh the watchdog in an interrupt routine
Secure the unused program memory area. Fill the unused memory locations with code
that forces a watchdog reset or jumps to a known program location if you do not want to
generate a reset
Input filtering. Its recommended to read the AVF signal during several AC line cycles.
