Register
R00, R20, R30 - DC Control Nominal, Margin High,
Margin Low Voltage
Settings
This register is combined with registers R01, R21
and R31 to set the 10-bit DC Control voltage value.
An explanation that shows the formula for setting
the DC Control voltage follows the register
descriptions.

Register
R01, R21, R31 - DC Control Nominal, Margin High,
Margin Low Voltage Settings
These register bits are combined with the register
R00, R20 and R30 to set the DC Control voltage
value.

The
DC Control Voltage setting bits (C[9:0])
are set using C[9:0] = 1024 * VREF_CNTL /
DC Control Voltage. VREF_CNTL is from registers R0C
and R0D.
The following table lists the registers with their
corresponding DC Control Mode:
