Issue 382585, Version 1.4
Note 2 does not list all of the available VCC_CLKIN voltages for banks 3B and 8B. Version 1.4 lists only 2.5V, but 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, and 3.3V are all supported voltages for VCC_CLKIN on banks 3B and 8B.
Issue 66844, Version 1.4
For the CRC_ERROR pin Note 24 will be removed since it has no relation to the CRC_ERROR pin.
The pin description will also be updated to reflect that the CRC_ERROR pin is always an open-drain pin if used as a CRC_ERROR pin and it is not a dedicated output where you can enable the CRC_ERROR pin as an open-drain in the CRC_ERROR Detection tab of the Device and Pin Options dialog box.
