CAT
4. CONFW.WEVSRC and CONFW.WEVEN are not correctly described in the user
1. Switch off discharge current when reaching 0V
2. CAT external capacitors are not clamped to ground when CAT is idle
3. DISHIFT field is stuck at zero
4. MGCFG2.ACCTRL bit is stuck at zero
5. MGCFG2.CONSEN field is stuck at zero
6. VERSION register reads 0x100
7. CAT asynchronous wake will be delayed by one AST peripheral event period
interface
CONFW.WEVSRC is only two bits instead of three bits wide. Only values 0, 1, and 2 can be
written to this register. CONFW.WEVEN is in bit position 10 instead of 11.
Fix/Workaround
Only write values 0, 1, and 2 to CONFW.WEVSRC. When reading CONFW.WEVSRC, dis-
regard the third bit. Read/write bit 10 to access CONFW.WEVEN.
The discharge current will switch off when reaching MGCFG1.MAX, not when reaching 0V.
Fix/Workaround
None.
The CAT module does not clamp the external capacitors to ground when it is idle. The
capacitors are left floating, so they could accumulate small amounts of charge.
Fix/workaround
None.
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 be deter-
mined only by the DILEN field.
Fix/Workaround
None.
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.
If the CAT detects a condition that should asynchronously wake the chip in Static mode, the
asynchronous wake will not occur until the next AST event. For example, if the AST is gen-
erating peripheral events to the CAT every 50 milliseconds, and the CAT detects a touch at
t=9200 milliseconds, the asynchronous wake will occur at t=9250 milliseconds.
Fix/Workaround
None.
