Data Conversion
Digit Designator
Example
half of D to receive the first 7-segment display code (rightmost or leftmost 8
bits) are designated in Di. If multiple digits are designated, they will be placed
in order starting from the designated half of D, each requiring two digits. If
more digits are designated than remain in S (counting from the designated
first digit), further digits will be used starting back at the beginning of S.
The digits of Di are set as shown below.
Digit number: 3 2 1 0

sions that they produce are shown below.
