33 P27 IN
Signal coming from touch key.
When any one of G-1 line keys on key matrix is touched, a corresponding signal from
P10 - P17 will be input into P27. When no key is touched, the signal is held at "L" level.
34 P26 IN
Signal similar to P27.
When any one of G-2 line key on key matrix is touched, a corresponding signal will be
input into P26.
35 P25 IN
Signal similar to P27.
When any one of G-3 line key on key matrix is touched, a corresponding signal will be
input into P25.
36 P24 IN
Signal similar to P27.
When any one of G-4 line key on key matrix is touched, a corresponding signal will be
input into P24.
37 P23 OUT
Segment data signals.
The relation between signals and indicators are as follows:
Signal Segment Signal Segment Signal Segment Signal Segment
P23............. P1 P17 ............. P5 P13 .............P9 P07 ........... P13
P22............. P2 P16 ............. P6 P12 ...........P10 P06 ........... P14
P21............. P3 P15 ............. P7 P11 ...........P11 P05 ........... P15
P20............. P4 P14 ............. P8 P10 ........... P12 P04 ........... P16
