Reset, Reset input. External Reset input is active low and enabled by unprogramming ("1") the
RSTDISBL Fuse. Pullup is activated and output driver and digital input are deactivated when the
pin is used as the RESET pin.
dW, debugWire channel. When the debugWIRE Enable (DWEN) Fuse is programmed and Lock
bits are unprogrammed, the debugWIRE system within the target device is activated. The
RESET port pin is configured as a wired -AND (open-drain) bi-directional I/O pin with pull-up
enabled and becomes the communication gateway between the target and the emulator.
• XTAL2, Bit 0
XTAL2, Oscillator. The PC0 pin can serve as Inverting Output for internal Oscillator amplifier.
