Data Outputting and Command Writing
In an operation to read key scan data, when
CS goes “Low” after Key Data Output Mode is entered, the DI/O pin
changes modes to OUTPUT and key data is output in synchronization with the rise of Shift Lock.
The waveforms to read key data are shown blow.
The DI/O pin enters the INPUT mode when the
CS pin is set to “High” after key data is output.
Keyscan stop

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
Display digit ................................... 24 digits
Brightness adjustment..................... 0/1024
All display lights ON or OFF .......... OFF mode
Segment output ............................... All segment outputs go “Low”
AD output....................................... All AD outputs go “Low”
ROW1 to 5...................................... All ROW outputs go “Low”
INT................................................. INT goes “Low.”
Be sure to execute the reset operation when turning power on and set again according to “Setting Flowchart”
after reset.
