8 Cortex-R5 PIL overview

A description of the Cortex®‑R5 Processor Integration Layer (PIL).

The Cortex‑R5 PIL integrates the Cortex‑R5 processor. The Cortex‑R5 processor might include one or two processors. The PIL also integrates:

All of the non-debug interfaces of the processor are exposed at the top-level of the PIL. The processor documentation describes these interfaces.

The Cortex‑R5 PIL has the following interfaces:

The PIL contains a single APB debug interface that can be asynchronous to the processor clock. It has one ATB trace output interface and an authentication interface. The following figure shows the Cortex‑R5 PIL.
