    _______________________________________________________

Details:

the registers OCR1BL0:OCR1BL7, OCR1BH0:OCR1BH7, OCR3BL0:OCR3BL7 and
OCR3AH0:OCR3AH7 are missing from the header file and where they should be
defined there are the registers with the names *A*n instead of *B*n defined.
(lines 693-710 and 802-819)

I'm not sure if the same code was copy-pasted to/from some other header files
because I have only looked at this file so far. I noticed this because it
redefined an already existing define for all the A values with the same
value.

What I also noticed but where I don't know if it's an issue: OCR2_0:OCR2_7 is
also defined twice. (once below OCR2A and once below OCR2B) I'm not sure if
this was intended because all other memory addresses usually have a different
naming and in the data sheet in 17.11.4 OCR2A – Output Compare Register A
and 17.11.5 OCR2A – Output Compare Register B they are named OCR2A[7:0] and
OCR2B[7:0] respectively instead of OCR2[7:0] (though changing these might
break programs relying on those defines)

I have also attached a patch (diff -rupN) which fixes the naming of the macros
mentioned in the bug title here but not the OCR2_n macros.
