Clock subsystem block diagram - IP modules.</P><P>On the LS1043ARDB the 32 KHz clock is applied to both inputs TA_BB_RTC and RTC.</P></BODY></HTML> Thu, 23 Mar 2017 03:01:50 GMT https://community.nxp.com/t5/Layerscape/Which-pin-used-RTC-or-TA-BB-RTC-used-for-WDOG-for-LS1043ARDB-and/m-p/609289#M1751 ufedor 2017-03-23T03:01:50Z
