The device revision E does not reset the COUNT system register on COMPARE match. In
this revision, the COUNT register is clocked by the CPU clock, so when the CPU clock
stops, so does incrementing of COUNT.
Fix/Workaround
None.
Fix/Workaround
Do not use the MPU.
MACB-WOL on GPIO9 (PA09), MACB-WOL on GPIO18 (PA18), USB-USB_ID on GPIO21
(PA21), USB-USB_VBOF on GPIO22 (PA22), and all function B and C on GPIO70 to
GPIO101 (PX00 to PX39).
Fix/Workaround
Do not use these alternate B and C functions on the listed GPIO pins.
Here is the table of Rev E
Fix/Workaround
Do not use on this silicon revision.
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
interrupt context will be pushed onto the stack while the core SR mode will indicate an
exception. A RETE instruction would then corrupt the stack..
Fix/Workaround
Follow the rules of the AVR32UC Technical Reference Manual. To increase software
robustness, if an exception mode is detected at the beginning of an interrupt handler,
change the stack interrupt context to an exception context and issue a RETE instruction.
