5.1 Serial Data Input
The serial data is input in synchronization with the rising of the CLOCK pin (pin 27) in the input status (the initial
status is “input”).
The last 4 bits read at the rising edge of the LOAD pin (pin 28) are identified and processed as a command.
Figure 5-2 shows the timing chart of serial data input.
Table 5-1 lists the serial data I/O commands.

Remarks 1.
For the data configuration of display data input, refer to
4. LCD DISPLAY FUNCTION
.
2.
For the data configuration of key data output, refer to
3. KEY SCAN
.
3.
Execute display data input before key data output.
4.
If a pulse is input to the LOAD pin without display data input, the device does not
operate.
5.
The device does not operate when data other than an I/O command is input.
