Hi guys. I have a problem here. I'm new to LPC2103, previously been using 8051. I will explain in 8051 register instead of LPC2103 and hope you can enlighten me.
In 8051, there is SBUF, RI and TI bits. I would like to know which registers does similar functions respectively in LPC2103.
Your help is greatly appreciated. Thanks!
Go to the list of ARM devices the Keil tools support:

Pick yours, download the data sheet and user manual, then look up UART.
Hi there. Thanks for the reply. I have seen the data sheet and user manual. but i am still unable to differentiate which registers acts like SBUF, RI and TI. In my opinion, i think that U0THR acts like a SBUF, RDR(bit0 of U0LSR) acts like a RI bit and THRE(bit5 of U0LSR) acts like a TI bit. Hope you can enlighten me further. Thanks!
Your question really has nothing to do with Keil software.
For specific questions about any manufacturer's device, you need to go to that manufacturer!
Have you looked at the Product Information Page (PIP) for the LPC2103 on the NXP website? That's the place to look for user manuals, application notes, and other supporting materials...
Have you looked here: http://www.keil.com/lpc/lpc2100_overview.asp Have you read the Hitex guide?
Or here: http://www.keil.com/download/list/arm.htm
The answer is: The LPC2000 series has complete new peripherals. We have plenty of examples (partly in the product partly on this web side) that explain the usage of these peripherals.
Without study of the data sheet / user's manual you cannot start using ARM based microcontrollers.
Thx for replying. I'll have a better look on data sheets.
"Without study of the data sheet / user's manual you cannot start using ARM based microcontrollers."
In fact, in general, Without study of the data sheet / user's manual you cannot start using any microcontroller nor, in fact, any other component.
