Dear Alls,

I used LPC908 for the pulses counter from digital kWh meter, so when WDT reset is occur, the data memory must not be lost.

The data memory will only saved to the flash code memory (using flash as data storage) when power is down. There's a power detector circuit.

Please tell me the value of Data Memory (included R0-R7) if the Watchdog RESET.

Please give me the solution if I want the data memory is not lost when the WDT reset is occur.

Thanks a lot.
