can be V
or V
for control pins, and V
or V
(High-Z) for RDY/
Busy
pin. The RDY/
Busy
is an
open drain output pin and indicates status of the internal WSM. When low, it indicates the WSM is
Busy performing an operation. A pull-up resistor of 10 k to 100 k
is required to allow the
RDY/
Busy
signal to transition high indicating a Ready WSM condition.
