with neat diagram explain the system bus structure of 8085
Vss, also known as Gnd, is pin 20 on the 8085.
HL is a register pair that is used to store 16-bit data in 8085 Microprocessor
A nibble (half-byte) is transferred in the 8085 by reading the destination, masking the alternate nibble, adding the nibble, and storing the result. For example, to store the low order nibble at location 1000H to the byte at location 1001H, you could use... LDA 1001H XRI 0F0H STA 1001H LXI H,1001H LDA 1000H XRI 0FH ADD M
in 8085 only one accumulator used where in 6800 used two accumulator.
In the 8085, the LDA instruction loads the accumulator from memory, while the STA instruction stores the accumulator to memory. LDA is a read, while STA is a write. LDA is opcode 3AH, while STA is opcode 32H.
LDA is an Intel 8085 opcode, 3AH, that loads that accumulator from a location specified in memory.

LDA first_number MOV B,A LDA second_number ADD B RRC XRI 7FH STA result This simply takes two numbers and adds them together. Then it divides the result by 2, by shifting to the right. The numbers are unsigned, and there is no handling for overflow.

LDA in terms of computer system architecture stands for Logical Device Address. A LDA is a one byte address (i.e an upper MAC address) and there is no physical address (i.e lower MAC address) specified.
