To program the microcontroller you will need to build or buy a programmer.
Here is a link to a programmer that you can build by yourself:

It is a waste of time for me to elaborate on this subject if you can read about it here: https://www.pjrc.com/tech/8051/dev-board-desc.html
(middle section). This site will also explain how to use external RAM etc.
Main thing, which you can find in the attached schematic diagram is that you need to fetch the lower part of the address (A7 -A0) and this is done by a 8-bit latch, such as 74373, controlled by the ALE pin, but this you will learn from that drawing ,,
pinnacle52 profasional is the best assambler and simulater. check its demo ver. (limit to 2k code).

i have worked on it. it is nice
Using 22.1184MHz crystal. if use timer 0 to measure time,configure Timer 0 as 16-bit time mode. if i want this Timer 0 to count up to 25ms then reset, what value should i put in the TH0 and TL0?
Below calculation is it correct?
22.1184MHz/12=1843200
0.025*1843200=46080
then TH0=0xB4, TL0=00
Thanks
