Microprocessor Interfacing and Embedded System

Exercise 7: Chapter 2 (V Hall) - (a) If code segment for an 8086 program starts at address 70400H, what number will be in the CS register ? (b) Assuming this same code segment base, what physical address will a code byte be fetched from if the instruction pointer contains 539CH ? Problem 14: Chapter 2 -Write the code a. Load the number 7986H into BP register b. Copy the BP register contents to the SP register c. Copy the contents of AX register to the DS register d. Load the number F3H into the AL register Problem 15: Chapter 2 -If the 8086 execution unit calculates an effective address of 14A3H and DS contains 7000H, what physical address will BIO produce ? -/12/2020 Microprocessor Interfacing and Embedded System Problem 16: Chapter 2 -If the data segment register contains 4000H, what physical address will the instruction MOV AL, [234BH] read ? Problem 17: Chapter 2 -If the data segment register contains 7000H, write the instruction that will copy the contents of DL to address 74B2CH Problem 18: Chapter 2 -Describe the difference between the instructions MOV AX, 2347H and MOV AX, (2347H]
