• CCB address......44H
• D1 to D54..........Display data
Dn (n = 1 to 54) = 1: Segment on
Dn (n = 1 to 54) = 0: Segment off
• BU .....................Control data for specifying normal mode or power saving mode
• SC......................Control data for specifying all segments on or off
Serial Data Transfer Example
When 29 or more segments are used all 80 bits of the serial data must be sent.

When fewer than 29 segments are used only the first 40 bits of the serial data can be sent. However, all 80 bits must be
sent after power is first applied.
