Can I drive signals into the DATA [1..4] pins after configuration in Altera devices where the DATA [1..4] pins are dedicated configuration pins?

Description

Yes, you can drive signals into the DATA [1..4] pins after configuration in Altera® devices where the DATA[1..4] pins are dedicated configuration pins.

These pins will be tri-stated after configuration is complete and the FPGA will ignore any signals that is being driven on them.

Refer to the respective device Pin Connection Guidelines to determine if DATA[1..4] pins are dedicated configuration or dual purpose I/O pins.
