CPU revision
ALU instructions
Revision 1, 2 and 3 of the AVR32UC CPU has the same instruction timings, except that the
divider in revision 2 and later is faster than in revision 1. Instructions only present in revision 2 or
3 of the CPU are explicitly noted.
This group comprises simple single-cycle ALU instructions like add and sub. The conditional
subtract and move instructions are also in this group. All instructions in this group, except ssrf to
bits 15 to 31, take one cycle to execute, and the result is available for use by the following
instruction.
