ACIFB
CAT
4. ADC channels six to eight are non-functional
5. VERSION register reads 0x100
1. Generic clock sources in sleep modes.
2. Negative offset
3. CONFW.WEVSRC and CONFW.WEVEN are not correctly described in the user
4. VERSION register reads 0x200
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
Do not write values larger than 0x1F to ACR.STARTUP.
ADC channels six to eight are non-functional.
Fix/Workaround
None.
The VERSION register reads 0x100 instead of 0x101.
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 static offset of the analog comparator is approximately -50mV
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 VERSION register reads 0x200 instead of 0x212.
Fix/Workaround
None.
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.
