Figure 118. Additional Scan Signal for the Two-wire Interface
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
inserted both for the 5V reset signal; RSTT, and the 12V reset signal; RSTHV.
Figure 119. Observe-only Cell
The AVR devices have many clock options selectable by fuses. These are: Internal RC Oscilla-
tor, External RC, External Clock, (High Frequency) Crystal Oscillator, Low Frequency Crystal
Oscillator, and Ceramic Resonator.
Figure 120
The Enable signal is supported with a general boundary-scan cell, while the Oscillator/Clock out-
put 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.
From System Pin
shows how each Oscillator with external connection is supported in the scan chain.
