• Port B, Bit 3 – RESET/dW/PCINT11
RESET: External Reset input is active low and enabled by unprogramming (“1”) the RST-
DISBL Fuse. Pullup 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 unpro-
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.
