Spartan-6 - Where is the INIT value that is shown in the Status Register sampled?
Description
Where is the INIT value that is shown in the Status Register sampled? Is it the value of an internal register or the value at the pin?
Solution
It is the pin itself with no register. After configuration the value may change unless the configuration interface is persisted as the INIT pin will be a user I/O at this stage. The value in the Status Register will still reflect the value at the pin.
