RW
IDENTICAL_FRAME_THRESHOLD: 
: Number of identical frames that display 
controller needs to exceed in order to transition to PSR active state in HW timer mode
15:11
0b
RW
DPLLA_POWER_DOWN_DELAY: 
programmable delay from main link powerdown to 
DPLLA powerdown. The delay is in number of cdclk clocks.

RW
DOUBLE_FRAMES_IN_PSR_ACTIVE_ENTRY: 
. If asserted, HW will send two frames 
with same SDP active setting when entry PSR active state. This bit is set if the vertical 
blanking time is less than 330us.
9
0b
RW
SOURCE_TRANSMITTER_STATE_IN_PSR_ACTIVE: 
. If asserted, HW will keep 
transmitter active during PSR active state and sends only idle symbols. If deasserted, 
HW will turn off transmitter during PSR active state. Display driver will keep this bit 
consistent with Source transmitter state in PSR active bit in DPCD register of the sink.
8
0b
RW
PSR_ACTIVE_ENTRY: 
This bit is only valid in PSR_mode is SW timer mode. If it is 
asserted, HW will transition into PSR_active state. If it is deasserted, HW will transition 
to PSR_inactive state. SW should not set or clear this bit more than once within one 
vblank period.
7
0b
RW
PSR_SINGLE_FRAME_UPDATE: 
In PSR persistent mode, SW set this bit before 
writing registers for a flip. After HW finishes signle frame update, it goes back to PSR 
active ? no RFB state. SW driver may send new single frame update request. 
Programming note: Reading this bit is updated at the next vblank. Writing this bit to 1 
will cause PSR FSM to perform single frame update automatically, no vblank is required. 
When single frame update is done, it will automatically go back to PSR active ? no RFB 
update. 60094[2:0] = 3b011.
