PA6CS—PA6/Comparator selection
0 = PA6 is used for the interrupt caused by PA6CS interrupt request.
1 = The comparator is used for the interrupt caused by PA6CS interrupt request.
Reserved—Must be 0.
The interrupt control (IRQCTL) register contains the master enable bit for all interrupts.
See
IRQE—Interrupt request enable
This bit is set to 1 by executing an
instruction, or by a direct register write of 1 to this bit. It is reset to 0 by executing a
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.
