Hello.I wrote a simple ASM-code in Keil Uvision. MCU ST10F273. Procedure calls in different addresses.If the procedure call is within the same page, then "warning 62" does not occur.There is a problem with "warning 62" when you jump from one page (AT code 0x4000) to another (AT code 0x20000).
I am finding the setup of the IDE difficult despite reading instructions.How to solve this problem? What is the best way to write code that calls a procedure from one page from another.
a00.asm (18) warning A62: VALUE TRUNCATIONProgram Size: data=0(near=0) const=0(near=0) code=30creating hex file from "a00"..."c" - 0 Error(s), 1 Warning(s).
