Functional description

6.1 Architectural overview

The LPC2917/2919/01 consists of:

• An ARM968E-S processor with real-time emulation support

• An AMBA multi-layer Advanced High-performance Bus (AHB) for interfacing to the

on-chip memory controllers

• Two DTL buses (an universal NXP interface) for interfacing to the interrupt controller

and the Power, Clock and Reset Control cluster (also called subsystem).
