I am trying to programming the TL16c2550, I can read the default states of the registers, but when I´m trying to write a data in something register, for example to write a data in the line control register or modem control register , and after write some data, I tryed to read the same register I can´t read the writed data. Could you please tell me what is the correct sequence in order to write a data in the uart registers?
I am programming the next steps:
put low state CS
load address to write in the address bus
load data to write in the data bus
put to low IOW
set high IOW
Could you please tell me if this is the sequency correct?
Thanks in advance
