Data Transfer Method and Command Write Method
Display control command and data are written by an 8-bit serial transfer.
Write timing is shown in the figure below.
Setting the
CS pin to "Low" level enables a data transfer.
Data is 8 bits and is sequentially input into the DA pin from LSB (LSB first).
As shown in the figure below, data is read by the shift register at the rising edge of the shift clock, which is input
into the
CP pin. If 8-bit data is input, internal load signals are automatically generated and data is written to each
register and RAM.
Therefore it is not necessary to input load signals from the outside.
Setting the
CS pin to "High" disables data transfer. Data input from the point when the CS pin changes from
"High" to "Low" is recognized in 8-bit units.
* When data is written to RAM (DCRAM, ADRAM, CGRAM) continuously, addresses are internally
incremented automatically.
Therefore it is not necessary to specify the 1st byte to write RAM data for the 2nd and later bytes.
Reset Function
Reset is executed when the
RESET pin is set to "L", (when turning power on, for example) and initializes all
functions.
Initial status is as follows:
Address of each RAM ......................................Address "00"H
Data of each RAM............................................All contents are undefined
General output port ..........................................All general output ports (P1 to P4) go "Low"
Display digit.....................................................24 digits
Brightness adjustment ......................................0/1024
All display lights ON or OFF ...........................OFF mode
Segment output ................................................All segment outputs (SEG1 to SEG35) go "Low"
Common output................................................All common outputs (COM1 to COM24) go "Low"
AD output ........................................................All AD outputs (AD1 to AD4) go "Low"
Please set the functions again according to "Setting Flowchart" after reset.
