4. SPI Glitch on RXREADY flag in slave mode when enabling the SPI or during the first
5. SPI Disable does not work in Slave mode
1. If the BOD level is higher than VDDCORE, the part is constantly under reset
1. Wrong PDCA behavior when using two PDCA channels with the same PID.
1. The TWI RXRDY flag in SR register is not reset when a software reset is performed.
1.
1. PA29 (TWI SDA) and PA30 (TWI SCL) GPIO VIH (input high voltage) is 3.6V max
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.
transfer
In slave mode, the SPI can generate a false RXREADY signal during enabling of the SPI or
during the first transfer.
Fix/Workaround
1. Set slave mode, set required CPOL/CPHA.
2. Enable SPI.
3. Set the polarity CPOL of the line in the opposite value of the required one.
4. Set the polarity CPOL to the required one.
5. Read the RXHOLDING register.
Transfers can now befin and RXREADY will now behave as expected.
Fix/workaround
Read the last received data then perform a Software reset.
If the BOD level is set to a value higher than VDDCORE and enabled by fuses, the part will
be in constant reset.
Fix/Workaround
Apply an external voltage on VDDCORE that is higher than the BOD level and is lower than
VDDCORE max and disable the BOD.
Fix/Workaround
The same PID should not be assigned to more than one channel.
Fix/Workaround
After a Software Reset, the register TWI RHR must be read.
Code execution from SDRAM does not work.
Fix/Workaround
Do not run code from SDRAM.
instead of 5V tolerant
The following GPIOs are not 5V tolerant : PA29 and PA30.
Fix/Workaround
Code execution from external SDRAM does not work
