UNO digital pins 0 to 7 are connected to Port D of the ATmega328 microcontroller while digital pins 8 to 13 are to Port B. You are to implement a function whose functionality is similar to pinMode(). The function allows the simultaneous configuration of multiple pins by using DDRB/DDRD and PORTB/PORTD internally. The function should be named as multi-pinMod) For example, a single function call to multi-pinMod should allow the configuration of . digital pins 3, 4, and 5 as OUPUT pins, digital pins 7 and 8 as INPUT pins, and digital pins 10 and 11 as INPUT_PULLUP pins. Note that the previous configuration of all the other digital pins should not be changed 1. Specify the function declaration, including all input arguments and the return data type (using void if no return value). Explain the meaning of each input argument. The function declaration should be designed so as to simplify the internal implementation (instead of to simplify the usage of the function). For example, you may assume users of the function know that digital pins 0 to 7 are connected to one port while digital pins 8 to 13 are to a different port. You may also assume users have knowledge about the microprocessor internal details. 2. Implement the function by using DDRB/DDRD and PORTB/PORTD internally. Do not use the Arduino pinMode) function.
