A 3-wire bi-directional bus (SCK, SI, SO) is used to control the DP1203F. The output signal, SO, is provided by the
DP1203F in opposition to the SCK and SI which needs to be provided by the external application as an 8-bit
microcontroller. An access Read or Write with the XE1203F is possible only when the enable signal is active
(active LOW).
For more information about the 3-wire bus, please refer to the XE1203F datasheet chapter; Serial interface
definition and principles of operation.
