Register
R06 - ADOC Control Command, Internal Regulator
Output Voltage, Fault Output Enabling,
Configuration Register Lock, COMP1, COMP2 Sensor
Configuration
The ADOC function may be always enabled upon
power-up or require a write command to begin the
process. This choice is made by Bit D[6].
The default setting is 'No Write Command Required'
meaning ADOC begins upon powerup. Bit D[5]
of this register selects the output voltage of the
internal regulator powered by 12VIN. This voltage
will power the SMM105 if the voltage on the VDD pin
is lower than this setting. Bit D[3]
disables the Fault output while the device is
margining. Bit D[2] of this register allows
the configuration registers to be locked. Locking
the configuration registers is irreversible and
therefore this option cannot be selected using the
GUI. Bits D[1:0] individually configure the
COMP1 and COMP2 sensors to detect under-voltage or
over-voltage. Bits D[7] and D[4]
are unused and should be set to 0.
