Hello, I'm trying to interface an Infineon TLE4263-2ES voltage regulator with a external watchdog figure. The microcontroller is from the Freescale S12G family. My question is kind of gereic, in a way. When I'm sending a pulse signal to the voltage regulator from the micro, at what frequency should I send the signal in? I will be using a timer based interrupt to do this. Attached are the watchdog and reset information from the voltage regulator datasheet. Any help is appreciated.
