This register set the Rest 1 to Rest 2 downshift time.
Rest1 Downshift time = R1D[7:0] x 16 x Rest1_Rate.
Default value: 31 x 16 x 20 ms (Rest1_Rate default) = 9,920 ms = 9.92 s
Min:
1 x 16 x 20 ms (Rest1_Rate min) = 320 ms
Max:
242 x 16 x 2.56 s (Rest1_Rate max) = 9,912 s = 165 min = 2.75 hr
All the above values are calculated base on 100 Hz Hibernate clock.

This register set the Rest 2 frame rate.
Rest2 frame rate = (R2R[7:0] + 1) x 10 ms.
Default value: 10 x 10 ms = 100 ms
Min:
2 x 10 ms = 20 ms
Max:
241 x 10 ms = 2,410 ms = 2.41 s
All the above values are calculated base on 100 Hz Hibernate clock.

This register set the Rest 2 to Rest 3 downshift time.
Rest2 Downshift time = R2D[7:0] x 128 x Rest2_Rate.
Default value: 47 x 128 x 100 ms (Rest2_Rate default) = 601.6 s = 10 min
Min:
1 x 128 x 20 ms (Rest2_Rate min) = 2560 ms = 2.56 s
Max:
242 x 128 x 2.56 s (Resr2_Rate max) = 79,298 s = 1,321 min = 22 hrs
All the above values are calculated base on 100 Hz Hibernate clock.
