Notes:
1. The 2.0x ratio that is supported on models 7 and 8/[7:0] is not supported on models 8/[F:8] or 9.
Instead, if BF[2:0] equals 110b, a ratio of 6.0x is selected.

Notes:
1. The 2.5x ratio that is supported on model 8/[F:8] and 9 is not supported on standard-power model
D. Instead, if BF[2:0] equals 100b, a ratio of 2.0x is selected.
