Altera Quartus II Settings File - Manual (Page 539)

ENABLE_PR_PINS
Allows you to enable the PR_REQUEST, PR_READY, PR_ERROR, PR_DONE, DCLK, and DATA[15..0]
pins. These pins are needed to support partial reconfiguration (PR) with an 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 errors, and the PR_DONE pin to indicate the device
finished programming. If this option is turned off, these pins are not available as PR pins when the device
operates in user mode and the dual-purpose programming pins are available as user I/O pins.
