Hi friends
I was trying to use DS12887 and I secceeded but I found something strange with it.
According to the datasheet for reading and writing time The 7th bit of register B (SET) should be Set and Reset you know, but I do it without any setting and resetting, why???
And I need a piece of information for using the data bus.
when using an external RAM or ROM with 8051, Port 0 and 2 prepare address and data and they can't be used for any other purpose, my question is: Even if we use timing and can't we share the data BUS( port 0)? for exmaple when we have a RTC , a LCD display, an A/D can't we share the Data BUS? I thing it's possible, what's your idea???
