Dear all,
Please anyone can help me?
Currenlty i have x2 32kB SRAM for data and code. I would like to add more External-IO port for my board. How can i connect the circuit? I have no problem for write data to External Output port but the External Input port have a problem.
I realize this Input connection will cause the SRAM read and Input data read will run it in synchronized. Because from the coding...
char Read_PORT( const int addr) { unsigned char da;
SRAM_ON = 0; // P3^4 Lo to read Input data only. da = XBYTE[addr]; // when read SRAM data = read Input data !! data run in synchronize. SRAM_ON = 1;
return da; }
How to overcome this problem? Please suggestion..
Thank you.

By stopping trying to solve the wrong problem. You appear to believe you can design hardware to match a given piece of software you apparently found somewhere, while you don't fully understand either. That's not the right way to do things. Not by a wide margin.
