DESCRIPTION
The MC2102 is specifically designed for LED and LED DISPLAY driver.
The MC2102 has max 13 segment output lines, max 7 grid output lines, one display memory,
control circuit, 4 line serial data interface, and max 10 x 2 matrix key scan .
The more detail spec is listed below as Table 1.1.
Those functions are all incorporated into a single chip to build a highly reliable peripheral device
for a single chip microcomputer.
It is very convenient to control for numeric display.

This pin outputs at CLK falling edge.
This pin inputs serial data at the rising edge of CLK signal.
1
CLK I
Serial clock input pin.
Input data is trigger at rising edge.
Output data is trigger at falling edge.
2
STB I
When this pin is HIGH, CLK signal is ignored.
The data input after the STB has fallen is processed 3
as a command.
