 *                           share the same IP. The changes include MCI, RTC. 
 *                           Added Clock Generation Unit initialization in

The Description of the sample software
===================

The sample software have been tested on Keil uVision MDK software development 
platform(RealView compiler in the backend). The target board is Nohau's LPC2800 
Eval. board.
 
The sample software includes, common library, peripheral APIs, and test modules
for the APIs. The common library include startup file, standard definition and
header files, processor specific setup module including PLL and CGU setup, 
generic interrupt handler and related APIs, timer routine, and scatter loading file. 

The peripheral directories included so far are USBMEM, USBUVC, MCI, timer, SDRAM, 
WDT, UART, RTC, I2S, DADC_DDAC, etc. 

Keil USB device Mass Storage Class(MSC) and Video Class(UVC) example for 
LPC23xx/lpc24xx have been used as the base for the LPC288x USB high-speed USB driver 
porting. http://www.keil.com/download/docs/336.asp
In the USB example, the device is configured as a self-powered with remote wakeup
enabled. For the compliance test, GPIO2 or GPIO3 is used as remote wakeup source.
As a self-configured device, JP20 jumper should be closed onto the "arrow"(delta) 
side, not on the "VCC" side.
To test low power mode and USB resume to wake up the uC, set USB_LOW_POWER_EVENT 
to 1 in usbcfg.h.
For I2S DAI/DAO, DDAC, DADC test, some H/W modification is needed, an usage note in 
MS Word format is provided. 

Known issues:

(1) In the existing silicon on Nohau board, DMA for MCI controller is not working 
due to a H/W issue. MCI_DMA_ENABLED should be defined as 0.

(2) All the Keil MDK projects have been tested. Although, RVDS project has been 
created for USMMEM, but not tested. Keil has the configuration Wizard to configure 
CGU and PLL. If Keil tool is not used, you can use the startup.s attached in the
COMMON directory and add the PLL configuration examples from "target.c".
