Configuring the option bytes for your application

The option bytes allow to configure the device hardware features and memory protection.

They are stored in a dedicated memory block. Refer to the option bytes section of the

STM8L152x6 datasheet for a detailed description.

STVP can be used to program the STM8L option bytes. It is part of the free software

package provided by STMicroelectronics. This easy-to-use tool has a graphical interface

allowing to read, write and verify the STM8 Flash programming memory, data EEPROM and

option bytes.

The STVP executable is available from the Windows start menu.

Open the STVP GUI and select Configure>Configure ST Visual Programmer from

the main menu toolbar. The configuration dialog box opens.

In the hardware list, select ST-LINK as programming board.

In the port list, select USB as the host PC port to which the ST-LINK is connected. Only

the ports that are compatible with the selected hardware are displayed.

in the programming mode list, select SWIM. The programming modes displayed

depend on your programming equipment.

In the device list, select STM8L152x6 as the ST microcontroller you are going to

program (see Figure 18).

Figure 18.

Select your MCU

Select the OPTION BYTE tab, and click Read >Current tab in the menu toolbar. All the

STM8L152C6T6 option bytes and their respective values are displayed in the window

(see Figure 19).
