Power-Up and Power-Down Requirements
The recommended power-up sequence is to apply VCC/VSS
first, then the potentiometer voltages. During power-up, the
data sheet parameters for the DCP do not fully apply until
1ms after VCC reaches its final value. The VCC ramp
specification is always in effect. In order to prevent unwanted
tap position changes, or an inadvertent store, bring the CS
and INC high before or concurrently with the VCC pin on
power-up.
