Serial data shift clock.
I
Data present on SIN are shifted to the LSB of the 16-bit shift register with the SCKI rising edge. Data
in the shift register are shifted toward the MSB at each SCLK rising edge. The MSB data of the
common shift register appear on SOUT.
I
Serial data input for the 16-bit common shift register.
When SIN is high, a '1' is written to the LSB of the common shift register at the rising edge of SCLK.
Serial data output of the 16-bit common shift register.
When FC9(BLANK Mode) = 0 and BLANK = LOW;
SOUT is connected to the bit 7 of the 16-bit shift register. Data are clocked out at the SCLK rising
O edge.
In other case:
SOUT is connected to the bit 15 of the 16-bit shift register. Data are clocked out at the SCLK rising
edge.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages are with respect to device ground terminal.
