aWire

I/O pins
5. CAT CONSEN field is stuck at zero
6. VERSION register reads 0x100
1. aWire PB mapping and PB clock mask number
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
The ACCTRL bit in the MGCFG2 register is stuck at zero and cannot be written to one. The
analog comparators will be constantly enabled.
Fix/workaround
None.
The CONSEN field in the MGCFG2 register is stuck at zero and cannot be written to a differ-
ent value. The CAT consensus filter does not function properly, so termination of QMatrix
data acquisition is controlled only by the MAX field in MGCFG1.
Fix/workaround
None.
The VERSION register reads 0x100 instead of 0x200.
Fix/Workaround
None.
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.
