ID:176703 Output enable ports of the bidirectional pins <name> and <name> with pseudo_differential I/O standard do not have the same inversion

CAUSE: You used a bidirectional pin with pseudo-differential I/O standard, and the same signal drives the output enable ports of the output buffers, but the output enable ports do not have the same inversion.

ACTION: Remove or insert the same inversion on one of the output enable ports.
