Hello; i am using Silabs C8051F360 that support external memory, and i am using 32k memory with latch for address/data multiplex. i am a little bit confused on how to configure keil or Cx51 compiler so that i can create many variables and large arrays. My application will not work if i have to write and read from the memory using MOVX instruction. Hope u reply
Make sure that your project mentions this memory. Then it is enough to declare your variable xdata - or switch to a memory model that will activate Erik M.
Let Keil worry about the assembler instructions needed to access the variables.
