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 will still be reflected in the interrupt status register.
