9 / 34 page LC75805PE No.A2119-9/34 Control data 17 bits CCB address 8 bits Display data for LCD 140 bits Fixed data 9 bits CCB address 8 bits Control data 148 bits Control data 49 bits CCB address 8 bits Display data for LED 48 bits Fixed data 12 bits DD 3 bits (2) When CL is stopped at the high level (Note 1) The input of serial data is taken in at the rising edge of CL, and latched at the falling edge of CE. In addition, this IC has the function that counts the number of CL clock to receive the correct serial data. That is to say, because it isn’t latched at the falling edge of CE when the number of the count of CL in each serial data is wrong, receiving wrong serial data can be prevented.
