_______________________________________________________
Details:
Incorrect structure definitions for PORT_t and CRC_t. PORT_t is missing REMAP
and has no reserved register at this offset, resulting in the PINxCTRL
registers effectively being inaccessible via the struct. CRC_t register has a
reserved address at offset 0x02 according to datasheet which is not reflected
in CRC_t definition.
Attached patch generated from a modified header for which these two functions
now work as tested with xmega 128A1U hardware. Should the patch be broken
these errors can easily be resolved with reference to a recent datasheet.
At first glance, these changes do not appear in the recent 1.8.1 release.
