• Port B, Bit 3 – RESET/dW/PCINT11
RESET: External Reset input is active low and enabled by un-programming ("1") the RST-
DISBL fuse. Pull-up is activated and output driver and digital input are deactivated when the
pin is used as the RESET pin.
dW: When the debugWIRE enable (DWEN) fuse is programmed and lock bits are un-pro-
grammed, the debugWIRE system within the target device is activated. The RESET port pin is
configured as a wire-AND (open-drain) bi-directional I/O pin with pull-up enabled and becomes
the communication gateway between target and emulator.
PCINT11: Pin change interrupt source 11. The PB3 pin can serve as an external interrupt
source for pin change interrupt 1.
