Interrupt Request Enable
This bit is set to 1 by executing an Enable Interrupts (EI) or Interrupt Return (IRET) 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, reset or by a direct register write of a 0 to this
bit.
0 = Interrupts are disabled.
1 = Interrupts are enabled.
[6:0]
