Power supply.
6
LD
I
When the LD is at the low level, the clock
input reception mode is entered. and data
can be uptaken by the 12-bit shift register.
Then at the threshold rising from low to
high, the 12-bit shift register value is loaded
to the D/A output register.
7
CLK
I
Shift clock input. With the rise of the shift
clock, the input signal from the DI is input
to the 12-bit shift register.
8
Dl
I
Serial data input. Input serial data 12 bits long.
