    I/O Ports
    All AVR ports have true Read-Modify-Write functionality when used as general digital
    I/O ports. This means that the direction of one port pin can be changed without uninten-
    tionally changing the direction of any other pin with the SBI and CBI instructions. The
    same applies for changing drive value (if configured as output) or enabling/disabling of
    pull-up resistors (if configured as input).
    Port B
    Port B is a 6-bit bi-directional I/O port.
    Three I/O memory address locations are allocated for the Port B, one each for the Data
    Register – PORTB, $18($38), Data Direction Register – DDRB, $17($37), and the Port
    B Input Pins – PINB, $16($36). The Port B Input Pins address is read only, while the
    Data Register and the Data Direction Register are read/write.
    All port pins have individually selectable pull-up resistors. The Port B output buffers can
    sink 20 mA and thus drive LED displays directly. When pins PB0 to PB7 are used as
    inputs and are externally pulled low, they will source current if the internal pull-up resis-
    tors are activated.
    The Port B pins with alternate functions are shown in Table 23.
    When the pins are used for the alternate function, the DDRB and PORTB Registers
    have to be set according to the alternate function description.
