Chip
aWire enable does not work in Static mode.
Fix/Workaround
None.
aWire CPU clock speed robustness
The aWire memory speed request command counter warps at clock speeds below approxi-
mately 5kHz.
Fix/Workaround
None.
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 part receives a wakeup either from the
WAKE_N pin or the AST.
Fix/Workaround
None.
aWire PB mapping and PB clock mask number
The aWire PB has a different PB address and PB clock mask number.
Fix/Workaround
Use aWire PB address 0xFFFF6C00 and PB clock (PBAMASK) 24.
VERSION register reads 0x200
The VERSION register reads 0x200 instead of 0x210.
Fix/Workaround
None.
WAKE_N pin can only wake up the chip from Shutdown mode
It is not possible to wake up the chip from any other sleep mode than Shutdown using the
WAKE_N pin. If the WAKE_N pin is asserted during a sleep mode other than Shutdown,
nothing will happen.
Fix/Workaround
Use an EIC pin to wake up from sleep modes higher than Shutdown.
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.
Shutdown mode is not functional
Do not enter Shutdown mode.
Fix/Workaround
None.
VDDIN current consumption increase above 1.8V
When VDDIN increases above 1.8V, current on VDDIN increases with up to 40uA.
Fix/Workaround
None.
Increased Power Consumption in VDDIO in sleep modes
If OSC0 is enabled in crystal mode when entering a sleep mode where the OSC0 is dis-
abled, this will lead to an increased power consumption in VDDIO.
