Name

Description

0IC[0]

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.

1IC[1]

Output Interrupt Type

‘0’ = Level interrupt

‘1’ = Edge interrupt

2IC[2]

Output Interrupt Polarity

‘0’ = Active Low / Falling Edge

‘1’ = Active High / Rising Edge
