The watchdog is configured and controlled using registers 8’h13 through 8’h15. These register are provided in table Table 10-10. The TCAN114x-Q1 watchdog can be set as a time-out, window or question and answer (Q&A) watchdog by setting 8’h13[7:6] to the method of choice. The time-out and window watchdog timer is based upon registers 8’h13[5:4] WD prescaler and 8’h14[7:5] WD timer and is in ms. See Table Table 10-10 for the achievable times. If using smaller time windows it is suggested to use the Time-out version of the watchdog. This is for times between 4 ms and 64 ms.
