This register is used to enable the interruption from a system related interrupt source
to the host. Regardless of whether or not the IESYSIOR bits are enabled, the
ISSYSIOR bits are still updated. Writing ‘1’ clears a bit in this register. Writing ‘0’ has
no effect.
One or more level transition in enabled GPIOs
Some of these bits might be set to '1' by hardware during normal operation. The content of
these bit is for internal operation and are not required for normal use of device.
