Only Bit-specific addressing based Solutions will be considered for this problem. Part (a) Write a C function Init that initializes Port B, pins 0, 1 and 4 as outputs, and pins 2 and 6 are to be made input. (Ignore pull-up, pull-down resistors or high-amp drivers for outputs). (10 Points) Part b) Assume the initialization in part a) has been executed. Write C function that produces pattern of {001,010,111,101} at pins {PB4, PB1, PB0} only when both inputs PB2 and PB6 are high. Otherwise the pins {PB4, PB1, PB0} are off.
