Byte Address
This register is non-volatile and will be maintained through power and reset cycles. A valid OEM password is required for access
to these registers.

Default Value
Serial Address
Byte Address
These registers are used for backing up the POH result during power cycles. At power-up, the POH meter selects the larger of
the two values as the initial count. Incremental results are stored in alternate register pairs. The power-on hour meter may be
reset or preset by writing to these registers. These registers are non-volatile and will be maintained through power and reset
cycles. A valid OEM password is required for access to these registers.
Default Value
Serial Address
Byte Address
The scratchpad registers are general-purpose non-volatile memory locations. They can be freely read from and written to any
time the MIC3001 is in OEM mode.

I START current level selection:
0000 = No I START current
0001 - 1111 = 0.375mA x I START [3:0]
I START is used to speed up the laser start-up
after a fault accures. The charging current
of the compensation cap starts from I START
instead of ramping up from 0.
