DDA[7:0] —Data Direction for Port A
0 = Bits set to zero to configure corresponding I/O pin for input only
1 = Bits set to one to configure corresponding I/O pin for output
Reset state is mode dependent. In single-chip or bootstrap modes, port B pins are high impedance in-
puts with selectable internal pull-up resistors. In expanded or test modes, port B pins are high order ad-
dress outputs and PORTB is not in the memory map.
DDB[7:0] — Data Direction for Port B
0 = Bits set to zero to configure corresponding I/O pin for input only
1 = Bits set to one to configure corresponding I/O pin for output
Reset state is mode dependent. In single-chip or bootstrap modes, port F pins are high-impedance in-
puts with selectable internal pull-up resistors. In expanded or test modes, port F pins are low order ad-
dress outputs and PORTF is not in the memory map.
