Default Value
Serial Address
Byte Address
Saturation faults are suppressed for a time, t FLTTMR , following laser turn-on. This avoids nuisance tripping while the APC loop
starts up. The length of this interval is (FLTTMR∞0.5ms), 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.

Default Value
Serial Address
Byte Address
This four-byte field is the password required for access to the OEM area of the MIC3001’s memory and registers. The byte at
address 250 (FA h ) is the most significant byte. This field is compared to the four-byte OEMPW field at serial address A2 h , byte
120 to 123. If the two fields match, access is allowed to the OEM areas of the MIC3001 non-volatile memory at serial addresses
A4 h and A6 h . The OEM password may be set by writing the new value into OEMPWSET. The new password will not take effect
until after a power-on reset occurs or a warm reset is performed using the RST bit in OEMCFG0. This allows the new password
to be verified before it takes effect. These registers are non-volatile and will be maintained through power and reset cycles. A
valid OEM password is required for access to this register.
