32072SH–AVR32–10/2012
AT32UC3A3
Fix/Workaround
Set to 1b bit CORRS4 of the ECCHRS mode register (MD). In C-code: *((volatile int*)
(0xFFFE2404))= 0x400.
DMACA
data
transfer
fails
when
CTLx.SRC_TR_WIDTH
is
not
equal
to
CTLx.DST_TR_WIDTH
Fix/Workaround
For any DMACA transfer make sure CTLx.SRC_TR_WIDTH = CTLx.DST_TR_WIDTH.
3.3V supply monitor is not available
FGPFRLO[30:29] are reserved and should not be used by the application.
Fix/Workaround
None.
Service access bus (SAB) can not access DMACA registers
Fix/Workaround
None.
10.2.2
Processor and Architecture
LDM instruction with PC in the register list and without ++ increments Rp
For LDM with PC in the register list: the instruction behaves as if the ++ field is always set, ie
the pointer is always updated. This happens even if the ++ field is cleared. Specifically, the
increment of the pointer is done in parallel with the testing of R12.
Fix/Workaround
None.
Hardware breakpoints may corrupt MAC results
Hardware breakpoints on MAC instructions may corrupt the destination register of the MAC
instruction.
Fix/Workaround
Place breakpoints on earlier or later instructions.
When the main clock is RCSYS, TIMER_CLOCK5 is equal to PBA clock
When the main clock is generated from RCSYS, TIMER_CLOCK5 is equal to PBA Clock
and not PBA Clock / 128.
Fix/Workaround
None.
10.2.3
MPU
Privilege violation when using interrupts in application mode with protected system
stack
If the system stack is protected by the MPU and an interrupt occurs in application mode, an
MPU DTLB exception will occur.
Fix/Workaround
Make a DTLB Protection (Write) exception handler which permits the interrupt request to be
handled in privileged mode.
10.2.4
USB
UPCFGn.INTFRQ is irrelevant for isochronous pipe
As a consequence, isochronous IN and OUT tokens are sent every 1 ms (Full Speed), or
every 125uS (High Speed).
