Serial Clock, Data Input/Output
(SCIO)
SCIO is a bidirectional pin used to transfer commands
and addresses into, as well as data into and out of, the
device. The serial clock is embedded into the data
stream through Manchester encoding. Each bit is rep-
resented by a signal transition at the middle of the bit
period.
