10.3.1 Overview

The PIC32CZ CA80/CA9x family of devices is centered around a multi-layer switch fabric called the System Bus Structure Exchange (SSX). This is shown as the Bus Matrix in the Block Diagram. The SSX consists of three crossbars and six shared Advanced Peripheral Bus (APB) target bridges, providing data connections between Initiators and Targets. The SSX operates at half the CPU clock frequency.
