The interrupt control register is used to configure the interrupt controller. It has global
enable interrupt mask bit that controls the interruption to the host.
‘0’ = Active low/falling edge
‘1’ = Active high/rising edge
‘0’ = Level interrupt
‘1’ = Edge interrupt (Pulse width of 200µs)
When this bit is written a ‘1’, it allows interruption to the host. If it is written with a ‘0’, then, it
disables all interruption to the host. Writing to this bit does not affect the INT_EN_MASK value.
