¡ Semiconductor
DEN , EXCK, DIN, DOUT
Serial control ports for MCU interface.
Reading and writing data are performed by an external MCU through these pins. Eight registers
with eight bits are provided on the devices.
DEN is the “Enable” control signal input, EXCK is the data shift clock input, DIN is the address
and data input, and DOUT is the data output.
Fig.3 shows the input/output timing diagram.
Table 1 shows the register map.
