| 7:4 | top_init | Used to select the timeout period that the watchdog counter restarts from for the first counter restart (kick). This register should be written after reset and before the watchdog is enabled. A change of the TOP_INIT is seen only once the watchdog has been enabled, and any change after the first kick is not seen as subsequent kicks use the period specified by the TOP bits. The timeout period (in clocks) is: t = 2**(16 + top_init)

| 3:0 | top | This field is used to select the timeout period from which the watchdog counter restarts. A change of the timeout period takes effect only after the next counter restart (kick). The timeout period (in clocks) is: t = 2**(16 + top)
