bit 7-0
VOUT<7:0>:
VOUT register bits can be changed at any time during power delivery, provided that
transitions from one code to another:
• are done step-by-step, by small VOUT increments. The speed of the transition is left to the user
and limited by the I
2
C writing interface speed.
• code transition shall take place only within the same VOUT Range. Crossing boundaries of
resolution ranges may cause VOUT glitches and it is not recommended.
See VOUT selection in table below:
Note 1:
Default Status settings at power-up can be changed at the factory. Standard selections are described in
Section 6.0 “MIC24045 Default Settings Values at Power-Up”
in the data sheet.
Overwriting default
settings by I
2
C has no permanent effect and values will return to factory default values upon power
cycling.
2:
The functionality of the MIC24045 at any output voltage selection is subject to limitations described in
Section 7.0 “Application Information”
, in the data sheet.

Reserved<7:1>:
Writing to these bits has no effect on the device operation.
bit 0
ClFF:
Clear Fault Flags bit. Writing ‘
1
’ to bit 0 will clear all Fault Flags. The ClFF bit is self-clearing and
it returns to ‘
0
’ as soon as the Fault Flags have been cleared.
