Semiconductor Data Transfer Method Command Write Method Display control command data written 8-bit serial transfer. Write timing shown figure below.
MSM9201-xx
Setting "Low" level enables data transfer. Data bits sequentially input into from (LSB first). shown figure below, data read shift register rise shift clock, which input into pin. 8-bit data input, internal load signals automatically generated data written each register RAM. Therefore necessary input load signals from outside. Setting "High" disables data transfer. Data input from point when changes from "High" "Low" recognized 8-bit units.
