DEN , EXCK, DIN, DOUT
Serial control ports for MCU interface. Reading and writing data is performed by an external
MCU through these pins. Total 8 registers with 8 bits are provided on the devices.
DEN is the “Enable” control signal input, EXCK is the data shift clock input, DIN is the address
, , anddatainput,andDOUTisthedataoutputfromwhichinverteddataofthecontentsofthe
register is output.
Fig.5 shows the input or output timing diagram.
