Note:
It might not be possible to clear the
source
of an interrupt simply by clearing its bit in the
INTSETCLR register. Thus, software must monitor the set/clear status of such interrupts.
To mask an interrupt, clear its bit in the
Interrupt Mask/Enable
register (
“Platform Interrupt Mask/Enable Register (INTMSKENA)” on page 63
). To enable the interrupt,
set its bit.
For more information about the peripherals and their interrupts, refer to the manufacturer’s data
sheet.
