For a displacement addressing mode using the register R1, with
R1 = 196,803,43210, and the displacement value is 12,39610, the
datum to be accessed is at the address?
Give six examples of memory addressing commands in Intel
assembly language two of each(register-memory, register offset with
an index, and perhaps one other) and explain what they are doing.
Why is there no Assembly command to move an item from one RAM
location to another directly?
Q2-B) Answer the followings:
I. Identify the addressing mode for Two of the following
instructions:
SBB AX,SI MOV [BX]+1234H,AL XCHG DL,[BP+20H]
II. True or False and why correct the false one:
1- A 20-bit address bus sports 20,000 memory addresses
2-A machine cycle refers to fetch an instruction
3-A memory with 256 addresses has 256 address lines

What is the purpose of the status register in PIC
microcontroller architecture? Draw this register and define the
function of each of its bits.
Find C, Z, and DC flag bits for each of the following codes:
a)
MOVLW 9FH

C = , Z = , DC =
b)
MOVLW 82H
ADDLW 22H
C = , Z = , DC =
c)
MOVLW 67H
