Channel n Interrupt Enable Bit:
This READ/WRITE bit is used to:
To enable Channel n for Interrupt Generation at the Channel
Level
To disable all Interrupts associated with Channel n within the
XRT75R12D
This is a "master" enable bit for each channel. This bit allows
control on a per channel basis to signal the Host of selected error
conditions.
If a bit is cleared, no interrupts from that channel will be sent to the
Host via the INT pin.
If the bit is set (logic 1), any generated interrupt in channel n that
has been enabled in the Interrupt Enable register (IERn) for the
channel will activate the INT pin to the Host.
0 - Disables all Channel n related Interrupts.
1 - Enables Channel n-related Interrupts. The user must enable
individual Channel n related Interrupts at the source level, before
they are can generate an interrupt.
