Port B (PB7..PB0) Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).The Port B output buffers have symmetrical drive characteristics with both high sink and source capability.As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated.The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not
