Saturation faults are suppressed for a time, tFLTTMR, following laser turn-on. This avoids nuisance tripping while the APC loop
starts up. The length of this interval is (FLTTMR x 0.5 ms), typical. A value of zero will result in no fault suppression.
A valid OEM password is required for access to this register. This register is non-volatile and will be maintained through power
and reset cycles.

Operation
1 = Interrupts are masked
0 = Interrupts are enabled
This bit is similar to the IE (Global Interrupt Enable) bit in the
User Control Register. The /INT output can only be asserted
if IE is high and OEMIM is low.
1 = Power-on Hour Meter enabled
0 = Power-on Hour Meter disabled
Always write as zero; reads undefined
1 = masked; 0 = enabled
1 = masked; 0 = enabled
1 = masked; 0 = enabled
1 = masked; 0 = enabled
