The state of port B (PB[7:0]) at reset is mode dependent. In single-chip
or bootstrap modes, port B pins are high-impedance inputs with
selectable internal pullup resistors (see
Resistors). Writes to DDRB can change any of the bits to outputs. In
expanded or test modes, port B pins provide the high-order address
lines ADDR[15:8] for external memory devices.
