... Serial Data Output The LC7219 and LC7219M both have an internal 28-bit shift register that comprise two bits representing the state of IN0 and IN1 (I and I , respectively), a 20-bit general-purpose counter address ( UL3) as shown in table 3. The shift register contents are clocked out on DO when the serial data output mode is selected as shown in figure 3. ...

... Serial Bus Data Transfer The LC7219 and LC7219M can both transfer data in three different modes-36-bit input data transfer, 24-bit input data transfer and 28-bit output data transfer. The transfer mode is selected by the four data bits on DI immediately prior to CE going HIGH as shown in figure 6 and table 4 ...
