Unimplemented instructions
CPU and Architecture revision
The following table shows the instructions with support for unaligned addresses. All other
instructions require aligned addresses.
Table 9-1.
The following instructions are unimplemented in AVR32UC, and will cause an Unimplemented
Instruction Exception if executed:
Two major revisions of the AVR32UC CPU currently exist. The device described in this
datasheet uses CPU revision 2.
The Architecture Revision field in the CONFIG0 system register identifies which architecture
revision is implemented in a specific device.
AVR32UC CPU revision 2 is fully backward-compatible with revision 1, ie. code compiled for
revision 1 is binary-compatible with revision 2 CPUs.
