ATmega169V/L
Figure 109. General Port Pin Schematic Diagram
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 Fig-
ure 110 is inserted both for the 5V reset signal; RSTT, and the 12V reset signal;
RSTHV.
