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.

The scratchpad registers are general-purpose non-volatile memory locations. They can be freely read from and written
to any time the MIC3000 is in OEM mode.
