The Interrupt Control (IRQCTL) register (Table 37) contains the master enable bit for all
interrupts.
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 Reset.
0 = Interrupts are disabled.
1 = Interrupts are enabled.
Reserved
These bits must be 0.
