[avr-libc-dev] [bug #27198] avr/iox128a1.h is missing definitions for calibration signature indexes

[Simon Küppers]

Follow-up Comment #3, bug #27198 (project avr-libc):

First, as I already said Im not so much into inline-assembler.

What comes to the nt's I don't know who converted it from nt to nt on the
long way of copy and pasting. In the text file it's correct.

I also haven't found a way to use ZH/ZL instead of r30, r31.

In this line
"ldi %[Idx], %[Rd]"
I just needed a temporary Register to copy the NVM_CMD_READ_CALIB_ROW_gc. So
i used this register. I almost believe that there is a better solution, which
is easier to understand.

The constraints I got from a German page
(http://www.rn-wissen.de/index.php/Inline-Assembler_in_avr-gcc).
It says "r" for any register, M for an 8 Bit Constant, m for a memory address
(I believe?) and d for an upper register. So I think anything should be fine,
but Im open to tips or hints.

I've already tested the assembly within the attached text-file and it works
so far. I can read all calibration row entries.
