Bit (
IRQE—Interrupt Request Enable
This bit is set to 1 by execution of an EI (Enable Interrupts) or IRET (Interrupt Return)
instruction, or by a direct register write of a 1 to this bit. It is reset to 0 by executing a DI
instruction, eZ8 CPU acknowledgement of an interrupt request or system exception,
Reset, or direct register write to 0.
