We are using P1022NXN2LFB processor in our design. We are using POWER_EN to control switchable supplies. When HRESET_B  will be deasserted? i mean, will it be deasserted after 'Always ON core supply' and 'Always ON I/O supply' are stable and before switching on switchable supplies or will it be deasserted after all the supplies are stable. We don't have any external system/supervisor to control the reset. So please let me know how can we control .HRESET_B.  and also please let me know  what is the state of HRESET_B in deep sleep mode
