Parallel Input/Output
4.4.1 PORTB — Port B data register
4.4.2 DDRB — Data direction register for port B
Technical Data
Data direction B (DDRB)
Port B data (PORTB)
The state of the pins on reset is mode dependent. In single chip or
bootstrap mode, port B pins are high-impedance inputs with selectable
internal pull-up resistors (see
expanded or test mode, port B pins are high order address outputs and
PORTB/DDRB are not in the memory map.
The bits may be read and written at any time and are not affected by
reset.
