(1-5) 4 line type serial interface
4 line serial interface by SDA and SCL is possible at chip selection state (CS=”L”)
When chip is not selected, internal shift register and counter are reset to initial value.
Serial input data from SDA are latched at the rising edge of serial clock (SCL) in the sequence

Make serial clock (SCL) “L” at the non-access period and after 8bit data transfer.
SDA and SCL signals are sensitive to external noise. To prevent mal-function, chip selector
state should be released (CS = “H”) after 8bit data transfer as shown in the following figure.
