5. Hardware breakpoints on MAC instructions may corrupt the destination registerof the
1. Privilege violation when using interrupts in application mode with protected system
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
1. The NER register always returns zero.
All the multiply instructions do not work.
Fix/Workaround
Do not use the multiply instructions.
MAC instruction.
Fix/Workaround
Place breakpoints on earlier or later instructions.
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.
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.
Fix/Workaround:
None.
