Table 3.5 Control register bit function description.
Figure 3.4 shows the typical operation of the serial interface of the ADC. The serial clock provides the
conversion clock and also controls the transfer of information to and from the ADC. One complete conversion
can be achieved with 24 ADC_DCLK cycles. The detailed behavior of the serial port interface can be found in
the datasheet of the ADC. Note that the clock (ADC_DCLK) and chip enable signals (SCEN) of the serial port
interface SHRAE the same signal I/O with LCD driver IC. Users should avoid controlling the LCD driver IC
and ADC at the same time when designing the serial port interface controller. Also, because the chip enable
signal (SCEN) inputted to the ADC comes up with a logic inverter, the logic level of the SCEN should be
inverse when it is used to control the ADC.
