Internal Voltage Reference
ATmega164P/324P/644P features an internal bandgap reference. This reference is used for
Brown-out Detection, and it can be used as an input to the Analog Comparator or the ADC.
9.1.1
Voltage Reference Enable Signals and Start-up Time
The voltage reference has a start-up time that may influence the way it should be used. The
start-up time is given in “System and Reset Characteristics” on page 332. To save power, the
reference is not always turned on. The reference is on during the following situations:
1.
When the BOD is enabled (by programming the BODLEVEL [2:0] Fuse).
2.
When the bandgap reference is connected to the Analog Comparator (by setting the
ACBG bit in ACSR).
3.
When the ADC is enabled.
Thus, when the BOD is not enabled, after setting the ACBG bit or enabling the ADC, the user
must always allow the reference to start up before the output from the Analog Comparator or
ADC is used. To reduce power consumption in Power-down mode, the user can avoid the three
conditions above to ensure that the reference is turned off before entering Power-down mode.
