3. Exceptions when system stack is protected by MPU
4. Multiply instructions do not work on RevD.
1. Sleep Mode activation needs additional A to D conversion
1. SPI Bad Serial Clock Generation on 2nd chip_select when SCBR = 1, CPOL=1 and
2. SPI Disable does not work in Slave mode
1. TWIM Version Register is zero
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 and MPU is configured so that
system stack is not readable in unprivileged mode.
Fix/Workaround
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 specific case.
2. Execute the RETE instruction.
All the multiply instructions do not work.
Fix/Workaround
Do not use the multiply instructions.
If the ADC sleep mode is activated when the ADC is idle the ADC will not enter sleep mode
before after the next AD conversion.
Fix/Workaround
Activate the sleep mode in the mode register and then perform an AD conversion.
NCPHA=0
When multiple CS are in use, if one of the baudrate equals to 1 and one of the others doesn't
equal to 1, and CPOL=1 and CPHA=0, then an additional pulse will be generated on SCK.
Fix/workaround
When multiple CS are in use, if one of the baudrate equals 1, the other must
also equal 1 if CPOL=1 and CPHA=0.
Fix/workaround
Read the last received data then perform a Software reset.
TWIM Version Register (VR) is zero instead of 0x100.
Fix/Workaround
None.
