Description
Input serial data at rising edge of shift clock,
starting from the low order bit.
Output serial data at the falling edge of the shift
clock, starting from low order bit. This is N-ch
open-drain output pin.
Initializes serial interface at the rising or falling
edge of the AD6312. It then waits for reception of
a command. Data input after STB falling is
processed as a command. While command data
is processed, current processing is stopped, and
the serial interface is initialized. While STB is
high, CLK is ignored.
Reads serial data at the rising edge, and outputs
data at the falling edge.
Connect resistor in between this pin and Vss to
set up the oscillation frequency.
Segment output pins
Multi-function pins, Segment output pins (Dual
function as key scan source)
Grid output pins
These pins are selectable for segment or grid
driving.
CMOS output
Data input to these pins is latched at the end of
the display cycle.
Logic power supply
Connect this pin to system GND.
Driver power supply
These pins constitute a 4-bit general-purpose
input port.
