can you please write the code using assembly language.
3. Traffic light controller simulation. Use port pins PC5-PCo of the XMEGA128A10 and green, yellow, and red LEDs to simulate a traffic light controller. The traffic patterns and durations for the east west and north-south traffic are given in Table H4.3. Write a program to control the light patterns. Assume that the delay function delaybytooms is available for your call. The multiple of 100 ms is passed in 116. The subroutine setSysCikto32 Mwith32 Mintosc is available for your call.

For the circuit shown in Figure 8.22, write a program to generate a waveform as shown in Figure HW4.4 from VOUTA. Assume that delayims subroutine is available. This subroutine delaytms generates exactly 1 ms delay. The subroutine setSysCikto32Mwith32MIntosc is available for your call.
