2. USART RXBREAK problem when no timeguard
3. USART Handshaking: 2 characters sent / CTS rises when TX
4. USART PDC and TIMEGUARD not supported in MANCHESTER
5. USART SPI mode is non functional on this revision
1. HMatrix fixed priority arbitration does not work
1. PBA max frequency
1. The address of Flash General Purpose Fuse Register Low (FGPFRLO) is 0xFFFE140C
2. The command Quick Page Read User Page(QPRUP) is not functional
Do not set the PBA maximum frequency higher than 30MHz.
In asynchronous mode the RXBREAK flag is not correctly handled when the timeguard is 0
and the break character is located just after the stop bit.
Fix/Workaround
If the NBSTOP is 1, timeguard should be different from 0.
If CTS switches from 0 to 1 during the TX of a character, if the Holding register is not empty,
the TXHOLDING is also transmitted.
Fix/Workaround
None.
Manchester encoding/decoding is not working.
Fix/Workaround
Do not use manchester encoding.
USART SPI mode is non functional on this revision.
Fix/Workaround
Do not use the USART SPI mode.
Fixed priority arbitration does not work.
Fix/Workaround
Use Round-Robin arbitration instead.
The Peripheral bus A (PBA) max frequency is 30MHz instead of 60MHz.
Fix/Workaround
on revB instead of 0xFFFE1410
The address of Flash General Purpose Fuse Register Low (FGPFRLO) is 0xFFFE140C on
revB instead of 0xFFFE1410.
Fix/Workaround
None.
The command Quick Page Read User Page(QPRUP) is not functional.
Fix/Workaround
None.
