About Data Communication Method with The Controller
1. About data communication method of 4 line type CCB format
The 4 line type CCB format is the data communication method of before. The LC75806PT must connect to the
controller as followings.

external wiring so that signal waveforms are not degraded.
*18. The (INT) pin is an input port for the key data read request
signal (a low level on DO) detection.

2. About data communication method of 3 line type CCB format
The 3 line type CCB format is the data communication method that made a common use of the data input DI in the
data output DO. The LC75806PT must connect to the controller as followings.

external wiring so that signal waveforms are not degraded.
*18. The (INT) pin is an input port for the key data read request
signal (a low level on DO) detection.
In this case, Applications must transfer the data communication start command before the serial data input (CCB
address “42H”, display data and control data transfer) or serial data output (CCB address “43H” transfer, key data read)
to avoid the collision of the data input signal DI and the data output signal DO.
Then applications must transfer the data communication stop command when the controller wants to detect the key data
read request signal (a low level on DO) during a movement stop of the serial data input and the serial data output.
