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.
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.
As a consequence, isochronous IN and OUT tokens are sent every 1ms (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.
Sleep Mode activation needs additional A to D conversion
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.
ISO7816 info register US_NER cannot be read
The NER register always returns zero.
Fix/Workaround
None.
The LIN ID is not transmitted in mode PDCM='0'
Fix/Workaround
Using USART in mode LIN master with the PDCM bit = '0', the LINID written at the first
address of the transmit buffer is not used. The LINID must be written in the LINIR register,
UPCFGn.INTFRQ is irrelevant for isochronous pipe
