Alternate Functions of Port B
The Port B pins with alternate function are shown in
Table 10-6.
• Port B, Bit 7 – RESET/ dW/ ADC10/ PCINT15
• RESET, Reset pin: When the RSTDISBL Fuse is programmed, this pin functions as a normal
• If PB7 is used as a reset pin, DDB7, PORTB7 and PINB7 will all read 0.
• dW: When the debugWIRE Enable (DWEN) Fuse is programmed and Lock bits are
I/O pin, and the part will have to rely on Power-on Reset and Brown-out Reset as its reset
sources. When the RSTDISBL Fuse is unprogrammed, the reset circuitry is connected to the
pin, and the pin can not be used as an I/O pin.
unprogrammed, 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.
