MSC1215-xx
Semiconductor
CH1-6
Analog voltage input pin for the A/D converter
COL1-4
Key matrix input pins
These pins are active "Low" and pulled up to "H" through built-in resistors except when "L" is
input by a pushed down key.
ROW1-3
Key matrix scanning output
Normally ROW1-3 output "L", by detecting the key switch to be pushed down or released, a
key scan starts, sending CS pulses two times and VF data, after above turning the CS pin to "L"
from "H". After scan stops, all the ROW outputs turn to "L".
OSC0, 1
RC oscillation input pins
A resistor and a capacitor are connected to these pins. (See figure below)
OSC1
OSC0
R
C
SEG1-17
Segment output pins
GRID1
,
2
Grid output pins
Output an inverted signal of a grid signal.
These pins are connected to inputs of external drivers (such as a PNP transistor).
