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 AD6315. 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
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 (Dual function as key
source)
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.
