How does emu8086 assembler work?
The emu8086 assembler supports user input by setting a predefined value 01 or 01H in the AH register and then calling interrupt ( INT ). It will take a single character from the user and save the ASCII value of that character in the AL register. The emu8086 emulator displays all values in hexadecimal. The emu8086 supports single character output.
How many flags are there in 8086?
Flag register: This is a 16-bit register of which 9 bits are used by 8086 to indicate current state of the processor. The nine flags are categorized into two groups. Status flags: Six status flags indicate the status of currently executing instruction. Control flags: There are three control flags that controls certain operations of the processor.
