_01
VSTR_B
This is the data input pin to the electric volume.
"Data 1" is an input for the “H” level, and "data 0" is an input for the "L" level.
(A high impedance state is prohibited.) When no data is sent, keep VDIN at the "L" level.
This is the clock input pin to the electric
volume.
The data of the VDIN pin is fetched to the
shift register at the clock rising edge.
When a clock with more than six bits data
is input, the data that had been read is
sequentially shifted at each clock pulse,
and the last six bits of data become
effective.
When the strobe signal goes low (set to "L"
level), the shift register contents are
fetched to the latch.
fetched to the latch is sent directly to the
electric volume, and consequently the
output voltage changes. When the strobe
signal goes high (set to "H" level), the latch
data is held.
