Description
16.7 msec
H : GND
L : -5V
26
INT2
IN
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
27
R81
OUT
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.
28
R82
OUT
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.
29
R83
OUT
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.
30
R90
OUT
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.
31
R91
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to R60 - R63 terminal while
one of G2 line keys on key matrix is touched.
32
R92
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to R60 - R63 terminal while
one of G1 line keys on key matrix is touched.
33
XIN
IN
Internal clock oscillation frequency setting input.
The internal clock frequency is set by inserting the capacitor-resistor oscillation circuit
with respect to XOUT terminal.
34
XOUT
OUT
Internal clock oscillation frequency control output.
Output to control oscillation input of XIN.
35
RESET
IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is supplied. Temporarily
set "L" level the moment power is supplied, at this time the LSI is reset. Thereafter set
at "H" level.
36
HOLD
IN/OUT
Connected to GND.
37
VLC
IN
Signal synchronized with commercial power source frequency.
Signal similar to VSS.
38
COM1
OUT

Connected to LCD (Pin No. C1)
39
COM2
OUT
Common data signal: COM2.
Connected to LCD (Pin No. C2)
40
COM3
OUT
Common data signal: COM1.
Connected to LCD (Pin No. C3)
41
COM4
OUT
Terminal not used.
42
VDD
IN
Power source voltage input terminal.
Connected to GND.
