Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to R60 - R63 terminal while
one of G8 line keys on key matrix is touched.
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to R60 - R63 terminal while
one of G7 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to R60 - R63 terminal while
one of G6 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to R60 - R63 terminal while
one of G5 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to R60 - R63 terminal while
one of G4 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to R60 - R63 terminal while
one of G3 line keys on key matrix is touched.
Terminal not used.
Internal clock oscillation frequency setting input.
The internal clock frequency is set by inserting the capacitor and resistor circuit with
respect to XOUT terminal.
Internal clock oscillation frequency control output.
Output to control oscillation input of XIN.
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is supplied. Temporarily set
to "L" level the moment power is supplied, at this time the LSI is reset. Thereafter set at
"H" level.
Signal synchronized with commercial power source frequency.
Signal similar to VSS.
Common data signal: COM1.
Connected to LCD (Pin No. C1)
Common data signal: COM2.
