1. Switch off discharge current when reaching 0V

3. DISHIFT field is stuck at zero
ADC channels six to eight are non-functional.
Fix/Workaround
None.
The VERSION register reads 0x100 instead of 0x101.
Fix/Workaround
None.
The static offset of the analog comparator is appriximately -50mV.
Fix/Workaround
None.
The ACIFB should not use RC32K or CLK_1K as generic clock source if the chip uses sleep
modes.
Fix/Workaround
None.
The VERSION register reads 0x200 instead of 0x212.
Fix/Workaround
None.
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.
