Because these shared interrupts are edge-triggered, it is possible to generate an interrupt
just by switching from one shared source to another. For this reason, an interrupt must be
disabled before switching between sources.
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 (Table 48) contains the master enable bit for all
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 regis-
ter write of a 0 to this bit.
0 = Interrupts are disabled.
1 = Interrupts are enabled.
Reserved—Must be 0.
