Reserved No Connect
This pin should be left disconnected in normal operation.
Connecting any of these pins may cause adverse effects and will
not be supported.
Reserved, Pull-down
This signal used in the XOR chain. It should be pulled to VSS via
a 1 to10 KΩ resistor.

Description
1.9V LVR Power Output Reference
Voltage control for an external 1.9V PNP transistor in order to
25 A
A
produce a linearly-regulated supply.
If the 1.9V internal voltage regulator control circuit is not used,
connect the CTRL_18 pin to VSS through a 10 KΩ resistor.
1.2V LVR Power Output Reference
Voltage control for an external 1.2V PNP transistor in order to
23 A
A
produce a linearly-regulated supply.
If the 1.2V internal voltage regulator control circuit is not used,
connect the CTRL_12 pin to VSS through a 10 KΩ resistor.
