Portd 0xff

WebThis code checks whether PIN 0 in PORTB is HIGH or LOW. If it is high then assigns A = true; Here, PINB --> Reads data from PORTB, (1< Make 0th bit as 1 and AND 's both values to know whether PIN 0 in PORTB is high or not.

When the USART Receiver is enabled this pin is configured as an input regardless of the value of DDD0. When the USART forces this pin to be an input, the pull-up can still be controlled by the PORTD0 bit. PCINT16: Pin Change Interrupt source 16.
