FUNCTIONAL DESCRIPTION
Operation
As shown in “Data Structure”, 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 field that selects the input block of data. Data input to the
DATA_IN pin is loaded into the 68-bit shift register, transferred to the 60-bit latch while the load signal is at “H”
level, and then output via the 60-dot segment driver.

Display data corresponding to COM5
Arbitrary data can be set for the dummy bits.
Select bit, C1 to C5, selects 60-bit latches that correspond to COM1 to COM5, respectively.
Therefore, if “1” is set for more than one select bit, data is set to all the corresponding 60-bit latches.
Example:
If “1” is set to all the select bits C1 to C5, the display data of D1 to D60 is set to all the 60-bit latches that
correspond to COM1 to COM5.
