ENABLE FLAG

Operation:

Flags Affected:

(IF)- 0IF

Description:

CLI (Clear Interrupt-enable flag) zeroes IF. When the interrupt-enable flag is cleared, the 8086 and 8088 do not recognize an external interrupt request that appears on the INTR line; in other words maskable interrupts are disabled. A non-maskable interrupt appearing on the NMI line, however, is honored, as is a software interrupt. CLI does not affect any other flags.

Encoding:
