What is the different between LXI and LHLD in 8085?
LHLD 2050 Means..copy content of 2050 and 2051 to HL pair
if
2050 -> 90H
2051->5AH
LHLD 2050 implies..
L -> 90H
H -> 5AH
LXI means..Load Register Pair with Immediate data.. 16bit data
LXI B ,2050H
Loads BC pair with value 2050H
B-> 20H
C-> 50H
Its similar to 2 MVI instruction
ie
MVI H,20H
MVI L,50H
which eventually implies..HL -> 2050H
the advantage of LXI over MVI is that LXI is 3 byte and requires 10T states.Two MVI instruction is 4Byte and require 14Tstates...

CM LXI is a representation of the number 961 in Roman system of numerals.... Explanation: I - 1 V- 5 X- 10 L- 50 C- 100 D- 500 M- 1000 CM- represents 900 ( 1000-100 ) LX- represents 60 ( 50+ 10 ) I - represents 1. therefore, CMLXI represents ( 900+60+1 ) 961.............

alto lxi is 800cc engine. & alto vxi is 1000cc engine.
It's up to you: don't use it, if you don't want.

== LXI== base model XI==
It was sold in a different country. In the third-generation Accord "LX" means it has a carburetor and "LXI" means fuel injection. Fourth-generation Accords are all fuel injected, so they sold them as LX in some countries and LXI in others.

It is: lxi or LXI are both equal to 61
