2. When CL is stopped at the high level

Figure 2

• 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.

Note: The following type of transfer cannot be used when fewer than 29 segments are used.
