High Frequency ACLL Voltage Compensation

RT3612EB provides positive offset to enhance performance

that only applies to high frequency ACLL. The positive

offset can be set through PIN-SETTING in PS1.

HFACLL_LIFT_PS1[1:0] is the related settings. The

related setting table is listed in Table 15. The default set

of HFACLL_LIFT_PS1[1:0]=00. Note that smaller setting

value represents higher positive offset. The final setting

must be based on actual measurement.
