Hi , im trying to interface my 89S52 with HT1621 its an LCD controller , but i've some problems understanding the datasheet , which can be downloaded from here
https://www.electro-tech-online.com/custompdfs/2009/03/1621PDF.pdf
1. How much is the time of the write signal's pulse width ?
2. I didnt understand what is the meaning of common and segements , im totaly newbie in this subject of interfacing this type of controller , what i understood is its selects an adress then save the data in it , and then ??
3. What are the constraints im going to face when writting the code for it ? i've to use an accurate delay of uS or nS ??
