aWire enable does not work in Static mode.
Fix/Workaround
None.
5.
VERSION register reads 0x200
The VERSION register reads 0x200 instead of 0x210.
Fix/Workaround
None.
6.
The aWire debug interface is reset after leaving Shutdown mode
If the aWire debug mode is used as debug interface and the program enters Shutdown
mode, the aWire interface will be reset when the device receives a wakeup either from the
WAKE_N pin or the AST.
Fix/Workaround
None.

I/O Pins
1.
PB10 is not 3.3V tolerant
PB10 should be grounded on the PCB and left unused.
Fix/Workaround
None.
2.
Analog multiplexing consumes extra power
Current consumption on VDDIO increases when the voltage on analog inputs is close to
VDDIO/2.
Fix/Workaround
None.
3.
PA02, PB01, PB04, PB05, and RESET_N have half of the pull-up strength
Pins PA02, PB01, PB04, PB05, and RESET_N have half of the specified pull-up strength.
Fix/Workaround
None.
4.
OCD MCKO and MDO[3] are swapped in the AUX1 mapping
When using the OCD AUX1 mapping of trace signals MDO[3] is located on pin PB05
and MCKO is located on PB01.
Fix/Workaround
Swap pins PB01 and PB05 if using OCD AUX1.
5.
The JTAG is enabled at power up
The JTAG function on pins PA00, PA01, PA02, and PA03, are enabled after startup. Normal
I/O module functionality is not possible on these pins.
Fix/Workaround
Add a 10kOhm pullup on the reset line.

Chip
1.
Power consumption in static mode is too high
Power consumption in static mode is too high when PA21 is high.
Fix/Workaround
Ensure PA21 is low.
2.
Shutdown mode is not functional
