1 ) In the Intel 8 0 8 6 / 8 0 8 8 microprocessor, the parity flag is set to 0 if the byte
In the Intel microprocessor, the parity flag is set to if the byte has an even number of s; otherwise, it is cleared.
aTrue
b False
The ALE is an active low signal in the Intel microprocessor
a True
bFalse
In the Intel microprocessor, both the address bus and data bus are bidirectional
aTrue
bFalse
The instruction MOV DS is not a valid instruction because:
a
The segement register is bits and the operand is larger than bit
b
To move information to the segment registers, the data must first be moved to a generalpurpose register, then to the segment register
c
The operand should be bracketed
d
The operand must first be placed in the CS register before moving it to the DS register
In the Intel microprocessor, the CF is set when there is a carry out, from d after an bit operation.
aTrue
bFalse
In the intel microprocessor, the default counter register is DX
aTrue
b False
If the instruction MOV AL starts at location : the next memory location available after execution of this instruction will be:
a
b
c
d
:
Six flags, called conditional flags, indicate some condition resulting after an instruction executes.
True
False
Given a starting address of : after the instruction MOV AL is executed the opcode will be stored:
a
In memory location :
b
In memory location :
c
In memory location :
d
None of the above
MOV BX DX is an example of what type of addressing mode?
a
Direct
b
Register
c
Immediate
d
Register Indirect
