AT32UC3A
Workaround/fix
The same PID should not be assigned to more than one channel.
15.3.7
GPIO
1.
Some GPIO VIH (input high voltage) are 3.6V max instead of 5V tolerant
Only 11 GPIOs remain 5V tolerant (VIHmax=5V):PB01, PB02, PB03, PB10, PB19, PB20,
PB21, PB22, PB23, PB27, PB28.
Workaround/fix
None.
15.3.8
USART
1.
ISO7816 info register US_NER cannot be read
The NER register always returns zero.
Fix/Workaround
None.
15.3.9
TWI
1.
The TWI RXRDY flag in SR register is not reset when a software reset is performed.
Fix/Workaround
After a Software Reset, the register TWI RHR must be read.
15.3.10
SDRAMC
1.
Code execution from external SDRAM does not work
Code execution from SDRAM does not work.
Fix/Workaround
Do not run code from SDRAM.
15.3.11
Processor and Architecture
1.
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.
2.
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.
3.
Exceptions when system stack is protected by MPU
RETS behaves incorrectly when MPU is enabled and MPU is configured so that
system stack is not readable in unprivileged mode.
Fix/Woraround
Workaround 1: Make system stack readable in unprivileged mode,
or
Workaround 2: Return from supervisor mode using rete instead of rets. This
requires :
1. Changing the mode bits from 001b to 110b 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 described in general
as not safe in the UC technical reference guide, it is safe in this very
