Description

en3

Enable.

If set, the corresponding interrupt will be enabled, otherwise it will be masked.

le3

Level/edge triggered.

If set, the interrupt will be edge-triggered, otherwise level sensitive.

pl3

Polarity

If set, the corresponding interrupt will be active high (or edge-triggered on positive edge). Otherwise, it will be

active low (or edge-triggered on negative edge).

28..24

isel3[4:0]

I/O port select.

The value of this field defines which I/O port (0 - 31) should generate parallel I/O port interrupt 3.

en2

Enable.

If set, the corresponding interrupt will be enabled, otherwise it will be masked.

le2

Level/edge triggered.

If set, the interrupt will be edge-triggered, otherwise level sensitive.

pl2

Polarity

If set, the corresponding interrupt will be active high (or edge-triggered on positive edge). Otherwise, it will be

active low (or edge-triggered on negative edge).

20..16

isel2[4:0]

I/O port select.

The value of this field defines which I/O port (0 - 31) should generate parallel I/O port interrupt 2.

en1

Enable.

If set, the corresponding interrupt will be enabled, otherwise it will be masked.

le1

Level/edge triggered.

If set, the interrupt will be edge-triggered, otherwise level sensitive.

pl1

Polarity

If set, the corresponding interrupt will be active high (or edge-triggered on positive edge). Otherwise, it will be

active low (or edge-triggered on negative edge).

12..8

isel1[4:0]

I/O port select.

The value of this field defines which I/O port (0 - 31) should generate parallel I/O port interrupt 1.

en0

Enable.

If set, the corresponding interrupt will be enabled, otherwise it will be masked.

le0

Level/edge triggered.

If set, the interrupt will be edge-triggered, otherwise level sensitive.

pl0

Polarity

If set, the corresponding interrupt will be active high (or edge-triggered on positive edge). Otherwise, it will be

active low (or edge-triggered on negative edge).

4..0

isel0[4:0]

I/O port select.

The value of this field defines which I/O port (0 - 31) should generate parallel I/O port interrupt 0.
