7.4 Port B
Port B is a 3-bit bidirectional port that does not share any of its pins with
other subsystems. The port B data register is located at address $0001
and its data direction register (DDR) is located at address $0005. Reset
does not affect the data registers but clears the DDRs, thereby setting
all of the port pins to input mode. Writing a 1 to a DDR bit sets the
corresponding port pin to output mode (see Figure 7-2).
