I/O
OUT Internal clock oscillation frequency control output.
Output to control oscillation input of XIN.
IN Power source voltage:-5V.
VC voltage of power source circuit input.
IN Signal coming from touch key.
When any one of G12 line keys on key matrix is touched, a corresponding signal will be
input into P27. When no key is touched, the signal is held at "L" level.
IN Signal similar to AN1.
When any one of G11 line keys on key matrix is touched, a corresponding signal will be
input into P26.
IN Signal similar to P27.
When any one of G10 line keys on key matrix is touched, a corresponding signal will be
input into P25.
IN Signal similar to P27.
When any one of G9 line keys on key matrix is touched, a corresponding signal will be
input into P24.
OUT Digit selection signal.
The relationship between digit signal and digit are as
follows;
Digit signal
P14 ........................... 1st.
P15 .......................... 2nd.
P16 .......................... 3rd.
P17 ........................... 4th.
(ß : INTO signal)
Refer to the touch control panel circuit about the relation
between signals and digits. Normally, one pulse is
output in every synchronized signal (ß) period, and input
to the grid of the fluorescent display.
OUT Digit selection signal.
OUT Segment data signal.
OUT Segment data signal.
OUT Segment data signal.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN1 and P27 - P24 terminal
while one of G7 line keys on key matrix is touched.
OUT Segment data signal.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN1 and P27 - P24 terminal
while one of G6 line keys on key matrix is touched.
OUT Segment data signal.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN1 and P27 - P24 terminal
while one of G5 line keys on key matrix is touched.
OUT Segment data signal.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN1 and P27 - P24 terminal
while one of G4 line keys on key matrix is touched.
OUT Segment data signal.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN1 and P27 - P24 terminal
while one of G3 line keys on key matrix is touched.
OUT Segment data signal.
