Com <---- This command is the comment command.
Com Enable the semihosting. If you don't use printf and/or scanf functions, set semihosting_enabled to 0.
Com Define the top of memory to store the buffer for semihosting calls.
Com Needed when working with an ICE Interface and if you use C printf/scanf functions in your code.
Com Disable all vector catch to not have AXD to warn you that a vector exception has been caught.
