FUNCTION DESCRIPTION

DATA TRANSFER FORMAT

1. Static (1/1) duty

2. 1/2 duty (if there are no more that 52 display segments, only 64 bits need to be transferred. The transfer format is the

same as the static duty case. It is not possible to alter the D54 to D106 data without specifying the D1 to D53 data.)

DP: Drive type selection bit

DP=0: 1/1 duty

DP=1: 1/2 duty

D1 to D106: Display data

Dn (for n=1 to 106)=0: Segment off

Dn (for n=1 to 106)=1: Segment on

x: don't care

DATA TRANSFER EXAMPLES

1. Static duty

2. 1/2 duty with 52 or fewer segments

3. 1/2 duty with more than 52 segments

Note: the following transfer format is not allowed in 1/2 duty with 52 or fewer segments.
