8. ADC measurement reports abnormal values with PSC2-synchronized conver-
9. ADC amplifier measurement is unstable
10. PSC emulation
11. Read / Write instructions of MUXn and REFS1:0 bits in the ADMUX Register
sions
When using ADC in synchronized mode, an unexpected extra Single ended conver-
sion can spuriously re-start. This can occur when the End of conversion and the
Trigger event occur at the same time.
Workaround
No workaround
When switching from a single-ended ADC channel to an amplified channel, noise can
appear on the next ADC conversion.
Workaround
After switching from a single ended to an amplified channel, discard the first ADC
conversion.
In emulation mode, TCNTn, OCRnx and ICRn 16-bit registers are accessed via the
TEMP register. This can induce an execution error, in step by step mode due to
TEMP register corruption.
Workaround
No workaround
during Analog conversion
During Analog conversion, the set or clear instructions of ADMUX channel and refer-
ence selection bits will fail.The bits of the temporary buffer will be written in place of
the final bits.
Workaround
Wait for the end of ADC conversion before any write of new channel or reference
selection values in ADMUX.
