KEA64 Watchdog Clock

[leekate-b45752]

Hello, 

When using 1kHz(Internal low power oscillator) for watchdog clock, the tolerance is about -33% to 25% according to the spec as below, so the error for the reset time of watchdog timeout is too big. Is there way to reduce it? Should I change the watchdog clock in order to reduce the to tolerance?
