This register is used to enable the interruption from a system related interrupt source
to the host. Writing ‘1’ in this register enables the corresponding interrupt event to
generate interrupt signal at the INT pin. Note that even if the interrupt is not enabled,
an interrupt event is still reflected in the interrupt status register.
One or more level transition in enabled GPIOs
Must be set to ‘0’ at all times.
System INT (A21, I2A, EOC)
Data available in FIFO. This interrupt can be cleared only if FIFO is empty.
