Chapter 39 of RM LS1021
Watchdog Timer (WDOG) All WDOG modules use 32 KHz clock, driven at device input RTC or TA_BB_RTC pin for their counters. The WDOG uses the low frequency reference clock (RTC) for its counter and control operations. The low frequency reference clock is a free-running clock and can't be gated.
Is this the case for the LS1043ARDB and is it the RTC or the TA_BB_RTC pins that are used for the LS1043ARDB, and which pin does the SDK 2.0 support for the LS1043ARDB for the counters for the WDOG modules?
