Result:

DX=0000, SP=06FD, BP=0000, SI=0000, IP=2007, FL=F006
Conclusion:
1. In each instruction, offset
address is incremented by 2 bit because 1 address is occupied by instruction
and the other saves the data.
2. If AL
is replaced by AH then the output will be
AX= 7700, BX=0054, CX=0000,
DX=0000, SP=06FD, BP=0000, SI=0000, IP=2007, FL=F006
3. If BL
is replaced by BH then the output will be

Result:
In this program we are finding positive
and negative no. from a given group of 5 numbers. The O/P generated is AX=
0080, BX=0000, CX=0000, DX=0302, SP=06FD, BP=0000, SI=2005. DH stores positive
number and DL stores negative number.

Experiment 9
Aim: WALP for interfacing of 8255
Programming Peripheral Interface (PPI) with 8086
Tool Required: Dyna Trainer Kit
Features of 8255:
The 8255A
is a programmable peripheral interface (PPI) device designed for use in Intel
microcomputer systems. Its function is that of a general purposes I/O component
to Interface peripheral equipment to the microcomputer system bush. The
functional configuration of the 8255A is programmed by the systems software so
that normally no external logic is necessary to interface peripheral devices or
structures. The important features are:
·
3 8-bit IO ports PA, PB,
PC
- PA
can be set for Modes 0, 1, 2. PB for 0,1 and PC for mode 0 and for BSR.
Modes 1 and 2 are interrupt driven.
- PC
has 2 4-bit parts: PC upper (PCU) and PC lower (PCL), each can be set
independently for I or O. Each PC bit can be set/reset individually in BSR
mode.
- PA
and PCU are Group A (GA) and PB and PCL are Group B (GB)
- Address/data
bus must be externally demux'd.
- TTL
compatible.
- Improved
dc driving capability
