DESCRIPTION OF LSI
I/O
IN
Signal coming from touch key.
When either G9 line on key matrix is touched, a corresponding signal out of P22 - P26 and P31
- P33 will be input into P50. When no key is touched, the signal is held at "H" level.
IN
Signal similar to P50.
When either G10 line on key matrix is touched, a corresponding signal will be input into P51.
IN
Signal similar to P50.
When either G11 line on key matrix is touched, a corresponding signal will be input into P52.
IN
Signal similar to P50.
When either G12 line on key matrix is touched, a corresponding signal will be input into P53.
IN
Connected to VSS.
IN
Connected to VSS.
_
Terminal not used.
IN
Power source voltage input terminal.
The power souce voltage to drive the LSI. Connected to GND.
IN
Power source voltage input terminal.
The power souce voltage to drive the LSI.
IN
Internal clock oscillation frequency input setting.
The internal clock frequency is set by inserting the resistor-capacitor oscillation circuit with
respect to X2 terminal.
Internal clock oscillation frequency control output.
Output to control oscillation input of X1.
IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied.
Terminal not used.
Back light circuit (Light emitting diodes) driving signal.
