Hi all,
I was trying to determine if these devices have multiply instructions or
not.
The datasheet doesn't show any MUL* instructions in the "Instruction Set
Summary" section, but the avr-libc documentation pages at:
http://www.nongnu.org/avr-libc/user-manual/using_tools.html
show these devices as "avr5" which has multiply instructions, and at
least avr-gcc 4.2.2 also emits multiply instructions for these devices.
Note that the AT90USB64x/128x variants do have MUL* instructions in
their datasheets.
Is this a bug in the current tools (binutils/gcc/documentation)?
