Key matrix
Key matrix scan signal output pins.
Normally low level is output.
Key scanning starts by detecting depression or release
of key matrix switch and continues until selection of key
scan stop mode.
When key scan stop mode is selected, all outputs of
ROW1 to 5 return to low level.
Reset input.
“Low” initializes all the functions.
Initial status is as follows.
Address of each RAM..............address “00”H
Data of each RAM...................Content is undefined
Display digit.............................24 digits
Brightness adjustment.............0/1024
All lights ON or OFF................OFF mode
ROW1 to 5..............................becomes low level
INT..........................................becomes low level
Pins for self-oscillation.
(Do not apply external clocks to these pins.)
Connect these pins to the crystal and capacitors or to
the ceramic resonator and capacitors.
The target oscillation frequency is 4.0MHz.
(The device has an internal feedback resister.)
