2. Assume you need to write an Arduino Mega 2560 C language program to generate a 3750Hz pulse train signal on PortB.3 using Timer 1 in Normal mode. The wave must have a 45% duty cycle (assume a 16 MHz CPU clock) Calculate the values to be loaded into the 16 bit timer/counterl special function register and specify the prescaler value you are using.
