2.2.9

ITC (Interrupt Controller)

2.2.9.1

Overview

The interrupt controller IP captures signal events and generates a maskable notify interrupt to the MCU

companion DIE.

2.2.9.2

Feature list

•

The IP controls 24 request lines

•

Interrupt output request level or pulse

•

Configurable parameters:

–

Rising edge interrupt capture request line

–

Maskable interrupt lines

–

Interrupt status interrupt

–

Readable interrupt sources active high

2.2.9.3

Functional description

This IP manages all the interrupt request lines within the AFE logic like error events and status events requiring

low latency notification and fast recovery actions from the MCU DIE.

The interrupt controller generates an interrupt whenever it detects an interrupt request rising edge transition and

the related interrupt line request line is enabled.

Here below is shown an outline view of the ITC block diagram.
