Bit 7
GO:
0 =
no change in the output voltage for the DCDC3 converter
1 =
the output voltage of the DCDC3 converter is changed to the value defined in DEFCORE with
the slew rate defined in DEFSLEW. This bit is automatically cleared when the DVM transition is
complete. The transition is considered complete in this case when the desired output voltage
code has been reached, not when the VDCDC3 output voltage is actually in regulation at the
desired voltage.
Bit 6
CORE ADJ Allowed:
0 =
the output voltage is set with the I2C register
1 =
DEFDCDC3 is either connected to GND or VCC or an external voltage divider. When
connected to GND or VCC, VDCDC3 defaults to 1.3 V or 1.55 V respectively at start-up
Bit 2– 0
0 =
the output capacitor of the associated converter is not actively discharged when the converter
is disabled
1 =
the output capacitor of the associated converter is actively discharged when the converter is
disabled. This decreases the fall time of the output voltage at light load
