Blank CDB for Your Application
Copy this worksheet as needed.
Write your own entries in this blank worksheet to suit your application.
Important: Because we cannot predict the number of bit, numeric, or ASCII
entries in your application, we give you a blank word column and extra rows
for each type of entry. Enter the number(s) of the file word(s) for each entry,
and use blank rows as needed. Enter data, ID, and addresses in the formats
that you specified in MCC word 1, bits 8-10. See notes [1] and [2] below.
