PA7VS—PA7/LVD Selection
0 = PA7 is used for the interrupt for PA7VS interrupt request.
1 = The LVD is used for the interrupt for PA7VS interrupt request.
PA6CS—PA6/Comparator Selection
0 = PA6 is used for the interrupt for PA6CS interrupt request.
1 = The Comparator is used for the interrupt for PA6CS interrupt request.
Reserved—Must be 0.
The Interrupt Control (IRQCTL) register
interrupts.
IRQE—Interrupt Request Enable
This bit is set to 1 by executing 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, Reset or by a direct
register write of a 0 to this bit.
0 = Interrupts are disabled.
1 = Interrupts are enabled.
Reserved—Must be 0.
