Option bytes configuration
The STM32 ST-LINK utility can configure all the option bytes via the Option Bytes dialog
box shown in
The Option Bytes dialog box contains the following sections:
●
●
●
Read Out Protection: Modifies the read protection state of the Flash memory.
For STM32 F-2 and STM32 L-1 series, read protection levels are available:
–
–
–
For the other devices, the read protection can only be enabled or disabled.
BOR Level: Brownout reset level. This list contains the supply level threshold that
activates/releases the brownout reset. This option is enabled only when connected to
an ultralow an STM32 F-2 or STM32 L-1 device.
For STM32 L-1 series, 5 programmable VBOR thresholds can be selected:
–
–
–
–
–
For STM32 F-2 series, 4 programmable VBOR thresholds can be selected:
–
–
–
–
User Configuration option byte:
–
–
–
Level 0: no read protection
Level 1: memory read protection enabled
Level 2: memory read protection enabled and all debug features disabled
BOR LEVEL 1: Reset threshold level for 1.69 to 1.8 V voltage range
BOR LEVEL 2: Reset threshold level for 1.94 to 2.1 V voltage range
BOR LEVEL 3: Reset threshold level for 2.3 to 2.49 V voltage range
BOR LEVEL 4: Reset threshold level for 2.54 to 2.74 V voltage range
BOR LEVEL 5: Reset threshold level for 2.77 to 3.0 V voltage range
BOR LEVEL 3:
BOR LEVEL 2:
BOR LEVEL 1:
BOR off:
WDG_SW : If checked, watchdog is enabled by software - otherwise it is
automatically enabled at power-on.
nRST_STOP: If not checked, reset is generated when entering Standby mode
(1.8V domain powered-off). If checked, no reset is generated when entering
Standby mode.
nRST_STDBY: if not checked, reset is generated when entering Stop mode (all
clocks are stopped). If checked, no reset is generated when entering Stop mode.
