Hello Kunal,

How I currently see this will be:

PSR mode: PR enabled
Source PSR ctl: enabled [0xXXXXXXXX]
Source PSR status: DEEP_SLEEP [0xXXXXXXXX]
Busy frontbuffer bits: 0x00000000
Performance counter: 0
Frame:	PSR2 SU blocks:
0	0
1	0
2	0
3	0
4	0
5	0
6	0
7	0
PSR2 selective fetch: enabled

I.e. PR mode w/ and w/o selective update/fetch.

BR,

Jouni Högander
