AT89C51- Datasheet

[Djsarkar]

Hi
I am having trouble to get correct information from the datasheet
Environment : AT89C51, Keil,
https://ww1.microchip.com/downloads/en/DeviceDoc/doc0265.pdf

I don't understand Which section/ page gives information to set UART?

 

[Ian Rogers]

The Atmel is a 8051 derivative ergo read the 8051 datasheet

http://lux.dmcs.pl/csII/8051.pdf page 19+ will help

Where I can find original datasheet of AT89C51 ? I want to find out required information for Uart from the datasheet

The object of an 51 derivative is that its able to run code from the original set..

This is the nearest.. https://ww1.microchip.com/downloads/en/DeviceDoc/doc4180.pdf

Alsothis.. https://ww1.microchip.com/downloads/en/DeviceDoc/doc4316.pdf

I think neither of them is the data sheet of my microcontroller.
I am sorry for not showing correct part in the firs post
I have AT89C512PI1503, Can you tell me the data sheet for this microcontroller?

That chip is still a AT89C51-24PI. The 1503 is just a date code. The -24PI is a version of the chip, 24Mhz, 40 pin DIP
Mouser has that chip, with a link to a datasheet:

Well done sagor1, so many knowledgeable people here.

Mike.

Actually, that "datasheet" is an abbreviated one, it does not show the UART details (I never checked it...)
The first link from Ian Rogers post #4 seems to have more details about each feature of the chip.

WTF is TF0 The timer overflow flag is the ET0 flag Also you need to enable ALL interrupts with EA.
Check my example.. https://www.electro-tech-online.com/articles/simple-interrupts-on-the-8051.654/

When you posted, I had edited my post because I got answer of my question.Your tutorial is awesome
