Serial Decoder Block Diagram
Example Timing Chart
Note: Driving the standby pin (pin 10) low resets the internal register.
The 9-bit serial data, input to the DA pin, is detected on the rising edge of CK, and then serially stored into
the 9-bit register.

The internal register is also reset in the default status upon power-on.
(1) The three bits in D8 to D6 select the register.
(2) The six bits in D5 to D0 specify the H-SW control mode or DAC output value.
(3) Data is output from the latch on the rising edge of the signal input to the LD pin.
