VSS

Ground.

AVSS

Shared analog Ground.

RSVD_VSS

Reserved Ground. This pin is reserved by Intel and may have factory test functions.

For normal operation, connect to ground.

RSVD_NC

Reserved No connect. This pin is reserved by Intel and may have factory test

functions. For normal operation, do not connect any circuit to these pins. Do not

connect pull-up or pull-down resistors.

No Connect. This pin is not connected internally.

Name and Function

CTRL12

1.2 V Control. LDO voltage regulator output to drive external PNP pass transistor. If

1.2 V is already present in the system, leave output unconnected. To achieve optimal

D3 power consumption, leave the output unconnected and use a high-efficiency

external regulator.

CTRL18

1.8 V Control. LDO voltage regulator output to drive external PNP pass transistor. If

1.8 V is already present in the system, leave output unconnected. To achieve optimal

D3 power consumption, leave the output unconnected and use a high-efficiency

external regulator.
