STM32H5 I3C dynamic address assignment

hi:

I have two NUCLEO-H563ZI EVB boards  and tried to implement I3C controller and target feature.

When ENTDAA was issued, I obtained the target 48-bit provisioned ID "0x020813810100" from waveform, I saw the description from I3C register  I3C_EPIDR ,it said" Bits[31:16] of the provisioned ID can be 0" but I got the actual value is "0x1381",so where is this value stored?

In addition, it seems that the target can issue a 48 bit provided ID without software operation , is this sending process entirely completed by MCU hardware?

So can I connect one ILPS28QSW and assign it to a dynamic address, then connect the second one with another dynamic address, so on so forth, finaly connect let's say 10 of them and get them working? THX!
