Preface
What's in This User's Guide
Chapter 1 – Overview
This Chapter lists the features of the LH79524/LH79525 SoC and presents a simplified
block diagram of the device, with the major architectural features identified. Also presented
is an overview of the ARM720T processor and MMU. The theory of operation covers bus
architecture, bus arbitration, and the base addresses for each of the Advanced High-Per-
formance Bus (AHB) and Advanced Peripheral Bus (APB) devices and the APB Bridge.
Coverage of the memory system includes memory mapping, memory remapping, and the
External Bus Interface (EBI). This Chapter provides programmer's models, programmable
parameters, default memory widths, address mapping, and includes a register summary
and register descriptions.
Chapter 2 – ADC and Brownout Detector
This Chapter describes the 10-channel, 10-bit Analog to Digital Converter, and its associ-
ated Brownout Detector. Theory of operation includes both touch-screen applications and
traditional ADC applications. This Chapter provides programmer's models, programmable
parameters, default memory widths, address mapping, and includes a register summary
and register descriptions.
Chapter 3 – Boot Controller
This Chapter describes alternate booting options, their use and configuration. Also
included is a programmer's model, address mapping, and a register summary and register
descriptions.
Chapter 4 – Color LCD Controller
This Chapter describes the Color LCD Controller (CLCDC) and the Advanced LCD Inter-
face Controller (ALI) functional blocks within the LH79524/LH79525. The Chapter includes
a brief overview, lists the types of panels supported, and at what bit-depths. The Chapter
also lists and explains the programmable parameters and includes a register summary.
Register descriptions, with reset values, and horizontal timing restrictions are provided.
Chapter 5 – DMA Controller
This Chapter describes the DMA operations available in the LH79524/LH79525 SoC,
latencies from one process to another, and the interrupts involved. Also included is a pro-
grammer's model, address mapping, and a register summary and register descriptions.
Chapter 6 – Ethernet MAC
Included in this chapter is a description and programming information for the SoC's Ether-
net MAC. Also included is a programmer's model, address mapping, and a register sum-
mary and register descriptions.
