#82859 - DPTR for code memory Responding to: ???'s previous message |
I need to check each bit of the controller of P2 independently and do certain tasks upon getting a high signal and low signal on a specific bit that;s why i wanted to know instead of using CJNE or JNZ commands can the ram location bits and DPTR lookup table be used but its hard to explain for all of you so just let me know whats how a lookup table works and where it is useful.
Iam having problem in getting a fresh page of 8052.com how i can remove this problem because other websites are working perfectly I have LAN for internet. I wanted to post another question but having problems with website refresh page. how to use Ram locations to make 4 Seconds counter ,same can be easily done with DJNZ or timers but if it is desired to make it using ram locations so that the counter of 4 seconds can be use at the same time controller doing some thing esle. |
