Increment (INC). The INC input is negative-edge triggered. Toggling INC will move the wiper and either increment or
decrement the counter in the direction indicated by the logic level on the U/D input.
Up/Down (U/D). The U/D input controls the direction of the wiper movement and whether the counter is incremented or
decremented.

R
Chip Select (CS). The device is selected when the CS input is LOW. The current counter value is stored in nonvolatile
memory when CS is returned HIGH while the INC input is also HIGH. After the store operation is complete, the X93155
will be placed in the low power standby mode until the device is selected once again.
