WebAs with the other flag bits, the processor clears IF in response to a RESET signal. The instructions CLI and STI alter the setting of IF. CLI (Clear Interrupt-Enable Flag) and STI (Set Interrupt-Enable Flag) explicitly alter IF (bit 9 in the flag register). These instructions may be executed only if CPL <= IOPL. WebIf EA = 1, interrupts will be enabled and will be responded to, if their corresponding bits in IE are high. If EA = 0, no interrupts will respond, even if their associated pins in the IE register are high.
