DMA data transfer Method and Interfacing with 8237/8257. e data can be recieved from 8255 to 8086;port b and port c lower act as ouput i,e data can be sent to 8255 A 3000 0000:3000 MOV AL, 99 ;I/O mode,mode 00(basic I/O mode),port A (PA0-7)input,Port C upper(PC4-7)input,10011;mode 0 for Group B,Group B(PB7-0) port B acts as output,Group B port C acts as inp(PC0-3),001 0000:3002 OUT 67, AL ;command. This information is mainly for the 8088 single board computer. Connect Power supply to 8086 kit 3. Intel 8255 Programmable Peripheral Interface. 9 Peripheral Interfacing—I IN THIS CHAPTER, YOU WILL LEARN The necessity of using dedicated hardware for peripheral interfacing. Compile the code into an EXE in an emulator preferrably emu8086. Introduction to MicroprocessorsObjectives, Introduction,. The CPU relinquishes the control of the bus before asserting the HLDA signal.
