FUNCTIONAL DESCRIPTION

Operation

As shown in "Data Structure" (next section), the display data consists of the data field

corresponding to the output for turning the segments on or off and the select field that selects

the input block of data. Data input to the DATA pin is loaded into the 88-bit shift register at the

rising edge of the CLOCK signal, transferred to the 80-bit latch while the load signal is at "H"

level, and then output via the 80-dot segment driver.
