Logic/Configuration Source and CPU Operating Mode at Power-up

5.7
Flash and user memory can contain different values for the Logic/Configuration Power-up
Source parameter. The following tables summarize how these settings determine the
logic/configuration source after a power cycle. CPU mode is affected by the
Power-up Mode and Stop-Mode I/O Scanning parameters, and the power down mode as
shown in the tables on page 85.
