Internal Voltage Reference
Voltage Reference Enable Signals and Start-up Time
Voltage Reference Characteristics
• Bit 1 – EXTRF: External Reset Flag
This bit is set if an External Reset occurs. The bit is reset by a Power-on Reset, or by writing a
logic zero to the flag.
• Bit 0 – PORF: Power-on Reset Flag
This bit is set if a Power-on Reset occurs. The bit is reset only by writing a logic zero to the
flag.
To make use of the Reset flags to identify a reset condition, the user should read and then
reset the MCUSR as early as possible in the program. If the register is cleared before another
reset occurs, the source of the reset can be found by examining the reset flags.
ATmega16/32/64/M1/C1 features an internal bandgap reference. This reference is used for
Brown-out DetectionDetection, and it can be used as an input to the Analog Comparators or
the ADC. The V
from the internal bandgap reference.
The voltage reference has a start-up time that may influence the way it should be used. The
start-up time is given in
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
3. When the ADC is enabled.
4. When the DAC is enabled.
Thus, when the BOD is not enabled, after setting the ACBG bit or enabling the ADC or the
DAC, the user must always allow the reference to start up before the output from the Analog
Comparator or ADC or DAC 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.
