When BIAS EN (Table 02h, Register 80h) is written to 0, writes to these bytes control the BIAS register, which then
updates a Maxim laser driver SET_IBIAS register.

MAN_CLK
BIT 7
BIT 0
When BIAS EN (Table 02h, Register 80h) is written to 0, MAN_CLK controls the updates of the MAN BIAS value to the
BIAS register. This new value is sent through the 3-wire interface. The values of MAN BIAS must be written with a
separate write command. Setting MAN_CLK to a 1 clocks the MAN BIAS value to the BIAS register, which then
updates a Maxim laser driver SET_IBIAS register.
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.
