CRC_ERROR_CHECKING
CRC_ERROR_CHECKING
Type
Specifies error detection CRC usage for the selected device. If error detection CRC is
turned on, the device checks the validity of the programming data in the device. Any
changes in the data while the device is in operation generates an error.
Using this feature in Stratix, Cyclone, or Stratix GX devices causes a reduction in
device speed.
Enabling this option puts the dual-purpose CRCERROR pin into configuration mode.
