|
| Errata | Added new errata:- ADC: When window monitor is enabled and its output is 0,
GCLK_ADC is kept running. Power consumption will be higher than
expected in sleep modes. Erratum reference: 14449
- ADC: The LSB bit of ADC result is stuck '0' in unipolar
mode for 8-bit and 10-bit resolution. Erratum reference:
14431
- Device: In IDLE sleep mode, the APB and AHB clocks are
not stopped if the FDPLL is running as a GCLK clock source.
Erratum reference: 13401
Changed errata:- Device: The low latency mode cannot be enabled by writing
'1' to 0x41008120. Erratum reference: 13506
Removed errata: |
