- Processor and Architecture
1. Local Busto fast GPIO not available on silicon Rev B
2. Memory Protection Unit (MPU) is non functional
3. Bus error should be masked in Debug mode
4. Read Modify Write (RMW) instructions on data outside the internal RAM does not
5. Need two NOPs instruction after instructions masking interrupts

Local bus is only available for silicon RevE and later.
Fix/Workaround
Memory Protection Unit (MPU) is non functional.
Fix/Workaround
Do not use the MPU.
If a bus error occurs during debug mode, the processor will not respond to debug com-
mands through the DINST register.
Fix/Workaround
A reset of the device will make the CPU respond to debug commands again.
work
Read Modify Write (RMW) instructions on data outside the internal RAM does not work.
Fix/Workaround
Do not perform RMW instructions on data outside the internal RAM.
The instructions following in the pipeline the instruction masking the interrupt through SR
may behave abnormally.
Fix/Workaround
Place two NOPs instructions after each SSRF or MTSR instruction setting IxM or GM in SR
Here is the table of Rev B
If the rules listed in the chapter `Masking interrupt requests in peripheral modules' of the
AVR32UC Technical Reference Manual are not followed, a spurious interrupt may occur. An
Do not use if silicon revison older than F.
