RZ/T1 MPUs endat info

Hello to all

I saw in the manual RZ/T1 (example R7S910018CBG) that the Endat function is defined as "optional" .... I don't understand ... if I take a "sample" of this MPUs in the Renesas website this function is present or not. If I look for a "sample" MPUs with the Endat function, how do I find it in the website?

Is the Endat function software or hardware?... in the example project in the Renesas website I don't understand, unfortunately the Endat libraries are pre-compiled

Thanks for the info
