Only 2^13 or 2^18 modes. Max time = 16M / 262144 = 16.4ms.
I know maybe it's hopeless.
Yes, the watchdog only has two timers 2^13 or 2^18, but also you can disable it.
But I do not know what is your application where you need a long watchdog timer, do you plan to have more than 17 ms on the same task that you can not feed the dog.
Thanks for your answer.
Long time can simplify coding.
Otherwise, I need feed the watchdog every where. For example: SCI transmit SPI transceiver and time delay.
