When BIAS-EN (Table 02h, Register 80h) is written to zero, bit zero of this byte will control the updates of the MAN IBIAS value to
the BIAS output. The values of MAN IBIAS should be written with a separate write command. Setting bit zero to a 1 will clock the
MAN IBIAS value to the output DAC for control of IBIAS.
1.
Write the MAN IBIAS value with a write command.
2.
Set the MAN_CLK bit to a 1 with a separate write command.
3.
Clear the MAN_CLK bit to a 0 with a separate write command.
