Finally the &= applies the logic "AND" between DDRD and 11111011 and the result is placed again in DDRD memory. Note: What the operator "AND" does is for each bit in the DDRD memory, it compares with the binary number above.

How to control arduino pins from registers without digitalWrite and ...

Port registers allow for lower-level and faster manipulation of the i/o pins of the microcontroller on an Arduino board. The chips used on the Arduino board (the ATmega8 and ATmega168) have three ports: 1. B (digital pin 8 to 13) 2. C (analog input pins) 3. D (digital pins 0 to 7) Each port is controlled by … See more Referring to the pin map above, the PortD registers control Arduino digital pins 0 to 7.
