Determine the stack contents after the execution of the following instruction sequence. Make sure to specify the updated Stack Pointer in your solution 1. lds ldaa ldab pshb #$2500 #$10 #$40 #$1550 ldx pshx 2. What is a subroutine mechanism? And illustrate with a figure the program flow involving a subroutine mechanism. 3. Write a subroutine to create a time delay of about 5seconds addressing the issue of preserving the CPU registers. Assume E clock frequency is 24MHz Write a program sequence to generate a tone of 125Hz for about a second and then stop, by interfacing with the speaker on the Dragon12_Light board. Assume E-clock of 12MHz 4. 5. Write a HCS12 assembly program to interface with the DIP switches using PORTH (PH7~PHO), such that when the PH3 bit is '1' irrespective of the other port bits then turn ON all the LEDs using PORTB otherwise turn OFF all the LEDs 6. Write a program sequence to interface with seven-segment display and the RGB LED on the Dragon12- Light board. Your program should display digit 2' on the DIGI and blue light on the RGB LED 7. What is an Interrupt and explain its purpose in Microcontroller Systems? Also discuss different types of interrupts and provide an example for eaclh
