Flash configuration
The option bytes allow the hardware configuration of the microcontroller to be selected.
They have no address in the memory map and can be accessed only in programming mode
(for example using a standard ST7 programming tool). The default content of the Flash is
fixed to FFh. To program directly the Flash devices using ICP, Flash devices are shipped to
customers with the internal RC clock source. In masked ROM devices, the option bytes are
fixed in hardware by the ROM code (see option list).

This option bit determines if a reset is generated when entering Halt
mode while the Watchdog is active.
0: No reset generation when entering Halt mode
1: Reset generation when entering Halt mode
This option bit selects the Watchdog type.
0: Hardware (Watchdog always enabled)
1: Software (Watchdog to be enabled by software)
These option bits enable the voltage detection block (LVD and AVD)
with a selected threshold for the LVD and AVD.
00: Selected LVD = Highest threshold (V
01: Selected LVD = Medium threshold (V
10: Selected LVD = Lowest threshold (V
11: LVD and AVD off
Caution: If the medium or low thresholds are selected, the detection
may occur outside the specified operating voltage range. Below 3.8V,
device operation is not guaranteed. For details on the AVD and LVD
threshold levels refer to
