What is the start sequence of AVDDR, AVE+ and ACM, after startup, is it need start time for stability?
Only SN8P1917/SN8P1919 can start AVDDR, AVE+, ACM, the proposed start order is:
(a). Enable BandGap; B0BSET FBGRENB=1
(b). Enable AVDDR; B0BSET FAVDDRENB=1
(c). Enable ACM; B0BSET FACMENB=1
(d). Enable AVE+; B0BSET FAENB=1
The proposed stable time after start each Regulator is at least 10ms.
