Voltage Reference Enable Signals and Start-up Time
When the Watchdog times out, it will generate a short reset pulse of one CK cycle duration.
On the falling edge of this pulse, the delay timer starts counting the Time-out period t

The voltage reference has a start-up time that may influence the way it should be used. The

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
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.
