Interrupt Control Register (ICR)
ICR register is used to configure the Interrupt Controller. It has a global enable interrupt
mask bit that controls the interruption to the host.

Global Interrupt Mask bit
When this bit is written a ‘1’, it will allow 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 IER value.
Output Interrupt Type
‘0’ = Level interrupt
‘1’ = Edge interrupt
Output Interrupt Polarity
‘0’ = Active Low / Falling Edge
‘1’ = Active High / Rising Edge
