... 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 running. Port B also serves the functions of various special features of the ATmega32A as listed on 59. 2.2.5 Port C (PC7:PC0) Port 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit) ...
