Environment: Arm Cortex processor STM32F103ZET6, on eval board Open103Z, Keil IDE, Windows 7.
in file stm32f10x.h there are a set of options defines that begin with:

#if !defined (STM32F10X_LD) && <and seven more is phrases>
...
/* #define STM32F10X_MD_VL */ /*!< STM32F10X_MD_VL: STM32 Medium density Value Line devices */
#define STM32F10X_HD /*!< STM32F10X_HD: STM32 High density devices */
...
I enabled the line shown. Several of the lines differ only in that one has "value line" and the other does not. What does "value line" mean?
 

Getting back to this after a long pause, I found this somewhere, but forgot where. As I recall, the value line is a higher speed verison. In the Micrium book it says the "access line" runs up to 36 MHz and the performance line runs up to 72MHz.
