30H
8085 RST6 Instruction: Target Memory Address
The 8085 microprocessor utilizes RST (Restart) instructions, which are similar to CALL instructions but jump to predefined memory locations. These locations are called vector addresses.
RST Instruction Vector Addresses
The vector address for an RST n instruction is calculated using the formula: Vector Address = n * 8 (where the address is in decimal).
The RST6 instruction corresponds to the value n=6.
- Calculating the decimal address:
$ n \times 8 = 6 \times 8 = 48_{10} $
- Converting the decimal address to hexadecimal:
$ 48_{10} = 30_{16} $
Therefore, the RST6 instruction transfers program execution to the memory location 30H.
