Design Tips
Question 1:
Answer 1:
The WDT was not designed to be a recovery from a brown-out condition. It was designed to
recover from errant software operation (the device remaining in the specified operating ranges).
If your system can be subjected to brown-outs, either the on-chip brown-out circuitry should be
enabled or an external brown-out circuit should be implemented.
Question 2:
Answer 2:
Make sure that the loop with the CLRWDT instruction meets the minimum specification of the WDT
(not the typical).
Question 3:
Answer 3:
On power-up, you must take into account the Oscillator Start-up time (Tost). Sometimes it helps
to put the CLRWDT instruction at the beginning of the loop, since this start-up time may be variable.
My system voltage drops and then returns to the specified device voltage
range. The device is not operating correctly and the WDT does not reset and
return the device to proper operation.
Device resets even though I do the CLRWDT instruction in my loop.
Device never gets out of resets.
