Note:
normal 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.
If PB7 is used as a reset pin, DDB7, PORTB7 and PINB7 will all read 0.
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.

output pin for the PWM mode timer function (c.f. OC1AX bit of TCCR1D register).
