PowerdownPin
Puts the pin into “sleep” mode by specifying whether or not the internal pullup on the pin
is enabled.
ProgPin
Adds an internal pull-up to the ProgPin pin. The Pullnone setting -disables the pullup. The
pull-up affects the pin after configuration.
ReadBack
This option allows you to perform the Readback function by creating the necessary
readback files.
When specifying the –g Readback option, the .rbb, .rbd, and .msd files are created.
If the –b option is used in conjunction with the –g Readback option, an ASCII readback
command file (file_name.rba) is also generated.
Security
Selecting Level1 disables Readback. Selecting Level2 disables Readback and Partial
Reconfiguration.
