This is not always true, because the interrupt enable bits controls when interrupts are allowed. Sometimes the main program need all 8 stack levels for making calls. CC5X will generate a warning for the critical functions. Using -q2 means an additional warning at stack level 7 if the interrupt routine requires 2 levels, i.e. contains function calls. CC5X supports the standard C constant data, including new memory pointer models.

This extension is compatible with the old operation. The bank type modifier defines the RAM bank to locate the variable. It can locate global variables, function parameters and local variables. However, the first definition defines the rambank, and later definitions must use the same bank. When defining a function prototype, this will normally not locate the function parameters.
