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