AT32UC3A3
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.
RETE instruction does not clear SREG[L] from interrupts
The RETE instruction clears SREG[L] as expected from exceptions.
Fix/Workaround
When using the STCOND instruction, clear SREG[L] in the stacked value of SR before
returning from interrupts with RETE.
RETS behaves incorrectly when MPU is enabled
RETS behaves incorrectly when MPU is enabled and MPU is configured so that system
stack is not readable in unprivileged mode.
Fix/Workaround
Make system stack readable in unprivileged mode, or return from supervisor mode using
rete instead of rets. This requires:
1. Changing the mode bits from 001 to 110 before issuing the instruction. Updating the
mode bits to the desired value must be done using a single mtsr instruction so it is done
atomically. Even if this step is generally described as not safe in the UC technical reference
manual, it is safe in this very specific case.
2. Execute the RETE instruction.
In the PRAS and PRBS registers, the MxPR fields are only two bits
In the PRAS and PRBS registers, the MxPR fields are only two bits wide, instead of four bits.
The unused bits are undefined when reading the registers.
Fix/Workaround
Mask undefined bits when reading PRAS and PRBS.
Multiply instructions do not work on RevD
All the multiply instructions do not work.
Fix/Workaround
Do not use the multiply instructions.
10.3.3
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.
10.3.4
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).
Fix/Workaround
For higher polling time, the software must freeze the pipe for the desired period in order to
prevent any "extra" token.
