The RESET pin accepts 5V active low logic for standard reset operation, and 12V active high
logic for High Voltage Parallel programming. An observe-only cell as shown in

Figure 25-5. Observe-only Cell
The AVR devices have many clock options selectable by fuses. These are: Internal RC Oscilla-
tor, External Clock, (High Frequency) Crystal Oscillator, Low-frequency Crystal Oscillator, and
Ceramic Resonator.

scan chain. The Enable signal is supported with a general Boundary-scan cell, while the Oscilla-
tor/clock output is attached to an observe-only cell. In addition to the main clock, the timer
Oscillator is scanned in the same way. The output from the internal RC Oscillator is not scanned,
as this Oscillator does not have external connections.
