ENABLE_PR_PINS
ENABLE_PR_PINS
Type
Enable the PR_REQUEST, PR_READY, PR_ERROR and PR_DONE pins. These pins are needed
for supporting partial reconfiguration with external host or external scrubbing. An
external host uses the PR_REQUEST pin to request partial reconfiguration or external
scrubbing, the PR_READY pin to determine if the device is ready to receive
programming data, the PR_ERROR pin to externally monitor programming error, and
the PR_DONE pin to indicate that the device has finished programming. If this option is
turned off, these functionalities are disabled when the device operates in user mode
and these pins are available as user I/O pins.
