Try-Before-Buy Mode Example
As shown in
Table 1
, it is possible to start the MMPF0100 directly from the TBBOTP registers without actually
programming the part. Shown below is an example of the Try-Before-Buy mode.
Note: All code examples in this document represent a script using the KITPFPGMEVME and the associated GUI.
Command syntax may vary if the user utilizes a different tool for communication.
