Rev. B
z DAC: AREF on PD0 is not available for the DAC
z ADC: Offset correction fails in unsigned mode
z EEPROM write and Flash write operations fails under 2.0V
z TWI Master or slave remembering data
z TWI SM bus level one Master or slave remembering data
z Temperature Sensor not calibrated
z Automatic port override on PORT C
z Sext timer is not implemented in slave mode
Issue:
DAC: AREF on PD0 is not available for the DAC
The AREF external reference input on pin PD0 is not available for the DAC.
Workaround:
No workaround. Only AREF on pin PA0 can be used as external reference input for the DAC.
Issue:
ADC: Offset correction fails in unsigned mode
In single ended, unsigned mode, a problem appears in low saturation (zero) when the offset correction is acti-
vated. The offset is removed from result and when a negative result appears, the result is not correct.
Workaround:
No workaround, but avoid using this correction method to cancel ΔV effect.
Issue:
EEPROM write and Flash write operations fails under 2.0V
EEPROM write and Flash write operations are limited from 2.0V to 3.6V. Other functionalities operates from 1.6V
to 3.6V.
Workaround:
None.
Issue:
TWI master or slave remembering data
If a write is made to Data register, prior to Address register, the TWI design sends the data as soon as the write to
Address register is made. But the send data will be always 0x00.
Workaround:
None.
