DISHIFT field is stuck at zero
The DISHIFT field in the MGCFG1, TGACFG1, TGBCFG1, and ATCFG1 registers is stuck
at zero and cannot be written to a different value. Capacitor discharge time will only be
determined by the DILEN field.
Fix/Workaround
None.
MGCFG2.CONSEN field is stuck at zero
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.
MGCFG2.ACCTRL bit is stuck at zero
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.
CAT asynchronous wake will be delayed by one AST event period
If the CAT detects a condition the should asynchronously wake the device in static mode,
the asynchronous wake will not occur until the next AST event. For example, if the AST is
generating events to the CAT every 50ms, and the CAT detects a touch at t=9200ms, the
asynchronous wake will occur at t=9250ms.
Fix/Workaround
None.
VERSION register reads 0x100
The VERSION register reads 0x100 instead of 0x200.
Fix/Workaround
None.
GLOC is non-functional
Glue Logic Controller (GLOC) is non-functional.
Fix/Workaround
None.
SAB multiaccess reads are not working
Reading more than one word, halfword, or byte in one command is not working correctly.
Fix/Workaround
Split the access into several single word, halfword, or byte accesses.
If a reset happens during the last SAB write, the aWire will stall
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 100ms.
aWire enable does not work in Static mode
