AM263P4: SWRV_APP reading in Secure Booting

Part Number: AM263P4


Hi,

It is noted that The EFUSE SWRV_APP is read and is passed as is by the HSM Boot ROM to the application via the Asset Interface. This EFUSE has a length of 192bits and the interpretation of this is left to the HSM Runtime developers. 

Why cannot HSM Runtime read EFUSE SWRV_APP directly? What are the assests left HSM Boot ROM after eclispsing?

Thanks
