 1.  Store 8-bit data in memory   Statement: Store the data byte 32H into memory location 4000H. Program 1: MVI A, 52H  : Store 32H in the accumulator STA 4000H  : Copy accumulator contents at address 4000H HLT              : Terminate program execution Program 2: LXI H           : Load HL with 4000H MVI M                   : Store 32H in the memory location pointed by HL register pair (4000H) HLT              : Terminate program execution The result of both programs will be the same. In program 1 direct addressing instruction is used, whereas in program 2 indirect addressing instruction is used. Exchange the contents of memory locations Statement: Exchange the con...

Demultiplexing Address/Data Bus AD7- AD0

Image
Demultiplexing Address/Data Bus AD7- AD0  Pin 30 of 8085 is the ALE pin which stands for ‘Address Latch Enable’. ALE signal is used to demultiplex the lower order address bus (AD0 – AD7). Pins 12 to 19 of 8085 are AD0 – AD7 which is the multiplexed address-data bus. Multiplexing is done to reduce the number of pins of 8085. Lower byte of address (A0 – A7) are available from AD0 – AD7 (pins 12 to 19) during T1 of machine cycle. But the lower byte of address (A0 – A7), along with the upper byte A8 – A15 (pins 21 to 28) must be available during T2 and rest of the machine cycle to access memory location or I/O ports. Now ALE signal goes high at the beginning of T1 of each machine cycle and goes low at the end of T1 and remains low during the rest of the machine cycle. This high to low transition of ALE signal at the end of T1 is used to latch the lower order address byte (A0 – A7) by the latch IC 74LS373, so that the lower byte A0 – A7 is continued to be available till the end of the m...
