I'm using the GINT0 (Group GPIO input interrupt) and want to trigger input change on GPIO. It works well with ports 0 and 1, but not on port 2.

Writing 0xFFFFFFFF to the PORT_ENA2 register read back as 0x00000000. Does it mean that the port 2 in not supported by the GINT ?

The user manual (UM10736 rev 1.1) does not show any limitation with port 2.
