Note:
1. ACMPVDD is a supply chosen by the setting in ACMPn_CTRL_PWRSEL and may be IOVDD, AVDD or DVDD
2. In ACMPn_CTRL register
3. In ACMPn_HYSTERESIS register
4. ±100 mV differential drive
5. In ACMPn_INPUTSEL register
The total ACMP current is the sum of the contributions from the ACMP and its internal voltage reference as given as:
I
ACMPTOTAL
= I
ACMP
+ I
ACMPREF
I
ACMPREF
is zero if an external voltage reference is used.
