Question
Please solve ALL parts of this ONE question. I dont have any more questions left on chegg so please answer them correctly in details. Thank you.
Programming Language: C
Write all code required to: a. enable continuouse monitoring of bits 4 and 5 of port B b. turn on the led attached to bit 1 of port B when bit 4 is low and bit 5 is high C. turn on led attached to bit 2 of port B when bit 4 is high and bit 5 is low. d. flash both LEDs on and off with ¼ second on-time and 1/5 second off-time when bits 4 and 5 are low e. turn off both LEDs when bits 4 and 5 are high. Hint: All checks should be inside of a single while loop. Hint: You will use no while-loops inside of the single while loop. Hint: for part d, turn on the leds for prescribed time and off for prescribed time only once each while-loop cycle. This will recurr each time through the loop as long as the input bits are unchanged resulting in the flashing pattern. Hint: each time the input pattern changes, you will need to be sure that both LEDs are placed in the correct state, so you will have to set the output correctly for both LEDs for each condition (b through e) above each cycle.Explanation / Answer
