BIT 0
When BIAS EN (Table 02h, Register 80h) is written to 0, bit 0 of this byte controls the updates of the MAN BIAS
value to the BIAS output. The values of MAN BIAS should be written with a separate write command. Setting bit 0
to a 1 clocks the MAN BIAS value to the output DAC.
1.
Write the MAN BIAS 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.
