may not meet the data sheet specifications (see
Figure 4-2). The wiper state may be unknown. Also, the
device may be capable of incrementing or decrement-
ing, if a valid command is detected on the CS and U/D
pins.

If the device V
age, care must be taken to ensure that the CS and U/D
pins do not “create” any of the serial commands.
When the device V
electrical performance may not meet the data sheet
specifications (see Figure 4-2). The wiper state may be
unknown. Also, the device may be capable of incre-
menting or decrementing, if a valid command is
detected on the CS and U/D pins.
When the device voltage rises from below the power-
up trip point (V
range, the wiper state will be forced to the default POR
wiper setting (see Table 4-1).
