This back end table can be used without modification for the Intel 8085 processor. Except for two additional instructions, the 8085 instruction set is identical and fully compatible with the 8080 instruction set. . All properties have the default size of two bytes, because one-byte registers also cover two bytes when put on the

Intel 8085 microprocessor is a general purpose microprocessor that has many interesting features. It can address and SP ( S ta ck Poin ter) contains the address of the last byte stored on the stack. 8085 executes a program by repeating the following set of actions. • Instruction Fetch. By default the constants are decimal.
All interrupts are enabled by the EI instruction and disabled by the DI instruction. In addition, the SIM (Set Interrupt Mask) and RIM (Read Interrupt Mask) instructions, the only instructions of the 8085 that are not from the 8080 design, allow each of the three maskable RST interrupts to be individually masked. All three are
