GLOC
I/O pins
2. SAB multiaccess reads are not working
3. If a reset happens during the last SAB write, the aWire will stall
4. aWire enable does not work in static mode
5. VERSION register reads 0x200
1. GLOC is non-functional
1. PB10 is not 3.3V tolerant
2. Analog multiplexing consumes extra power
3. PA02, PB01, PB04, PB05, RESET_N have half of the pullup strength
4. OCD MCKO and MDO[3] are swapped in the AUX1 mapping
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.
Reading more than one word, halfword, or byte in one command is not workingcorrectly.
Fix/workaround
Split the access into several single word, halfword, or byte accesses.
If a reset happens during the last word, halfword or byte write the aWire will wait forever for
an acknowledge from the SAB.
Fix/workaround
Reset the aWire by keeping the RESET_N line low for 100 ms.
aWire enable does not work in static mode.
Fix/workaround
None.
The VERSION register reads 0x200 instead of 0x210.
Fix/Workaround
None.
Gloc is non-functional.
Fix/workaround
None.
PB10 should be grounded on the PCB and left unused.
Fix/workaround
None.
Current consumption on VDDIO increases when the voltage on analog inputs is close to
VDDIO/2.
Fix/workaround
None.
Pins PA02, PB01, PB04, PB05, RESET_N have half of the specified pullup strength.
Fix/workaround
None.
When using the OCD AUX1 mapping of trace signals MDO[3] is located on pin PB05
and MCKO is located on PB01.
