Which pin used RTC or TA_BB_RTC used for WDOG for LS1043ARDB and SDK 2.0?

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?

WDOG receives a clock which is ORed version of TA_BB_RTC and RTC - please refer to the QorIQ LS1043A Reference Manual, Figure 4-7. Clock subsystem block diagram - IP modules.

On the LS1043ARDB the 32 KHz clock is applied to both inputs TA_BB_RTC and RTC.
