 <h1 id="purpose">Purpose</h1>
 <p>This driver provides the CMSIS device for the stm32wbxx products. This covers</p>
 <ul>
 <li>STM32WB55xx devices</li>
 <li>STM32WB5Mxx devices</li>
 <li>STM32WB50xx devices</li>
 <li>STM32WB35xx devices</li>
 <li>STM32WB30xx devices</li>
 <li>STM32WB15xx devices</li>
 <li>STM32WB10xx devices</li>
 <li>STM32WB1Mxx devices</li>
 </ul>
 <p>This driver is composed of the descriptions of the registers under “Include” directory.</p>
 <p>Various template file are provided to easily build an application. They can be adapted to fit applications requirements.</p>
 <ul>
 <li>Templates/system_stm32wbxx.c contains the initialization code referred as SystemInit.</li>
 <li>Startup files are provided as example for IAR©, KEIL© and STM32CubeIDE©.</li>
 <li>Linker files are provided as example for IAR©, KEIL© and STM32CubeIDE©.</li>
 </ul>
 <h1 id="specific-consideration-for-available-flash-size-inside-linker-file">Specific consideration for available FLASH size inside linker file</h1>
 <p>The available flash size depends on the wireless binary used inside the STM32WB device.</p>
 <p>The linker files templates for IAR, KEIL and GCC provide example of implementation which can be tuned.</p>
 <p>You can refer to the below chapters to optimize the usage of the flash on your device.</p>
 <h2 id="stm32wb55xx-stm32wb50xx-and-stm32wb5m">STM32WB55xx, STM32WB50xx and STM32WB5M</h2>
 <p>The default linker file provided in “/Drivers/CMSIS/Device/ST/STM32WBxx/Source/Templates” allows the application to use 512KB of flash.</p>
 <p>The maximum flash memory that can be used by the application is up to the Secure Flash Start Address (SFSA) that can be read from the option byte.</p>
 <p>The __ICFEDIT_region_ROM_end__ in the linker can be modified with a value up to : (0x08000000 + (SFSA &lt;&lt; 12)) - 1.</p>
 <p>Example:</p>
 <ul>
 <li>When the SFSA option byte is set to 0xA0, the maximum value to be used for __ICFEDIT_region_ROM_end is 0x0809FFFF which is 640KB of flash.</li>
 </ul>
 <p>Note:</p>
 <ul>
 <li>The SFSA option byte can only be set by the CPU2. The user cannot modify that value.</li>
 </ul>
 <h2 id="stm32wb35xx-and-stm32wb30xx">STM32WB35xx and STM32WB30xx</h2>
 <p>The default linker file provided in "/Drivers/CMSIS/Device/ST/STM32WBxx/Source/Templates allows the application to use 120KB of flash.</p>
 <p>The maximum flash memory that can be used by the application is up to the Secure Flash Start Address (SFSA) that can be read from the option byte.</p>
 <p>The __ICFEDIT_region_ROM_end__ in the linker can be modified with a value up to : (0x08000000 + (SFSA &lt;&lt; 12)) - 1.</p>
 <p>Example:</p>
 <ul>
 <li>When the SFSA option byte is set to 0x32, the maximum value to be used for __ICFEDIT_region_ROM_end is 0x08031FFF – which is 200KB of flash</li>
 </ul>
 <p>Note:</p>
 <ul>
 <li>The SFSA option byte can only be set by the CPU2. The user cannot modify that value.</li>
 </ul>
 <h2 id="stm32wb15xx-stm32wb10xx-and-stm32wb1mxx">STM32WB15xx, STM32WB10xx and STM32WB1Mxx</h2>
 <p>The default linker file provided in "/Drivers/CMSIS/Device/ST/STM32WBxx/Source/Templates allows the application to use 110KB of flash.</p>
 <p>The maximum flash memory that can be used by the application is up to the Secure Flash Start Address (SFSA) that can be read from the option byte.</p>
 <p>The __ICFEDIT_region_ROM_end__ in the linker can be modified with a value up to : (0x08000000 + (SFSA &lt;&lt; 11)) - 1 considering minimum CPU secure area size is one sector (2kBytes).</p>
 <p>Example:</p>
 <ul>
 <li>When the SFSA option byte is set to 0x37, the maximum value to be used for __ICFEDIT_region_ROM_end is 0x0801B800 – which is 110kB of flash</li>
 </ul>
 <p>Note:</p>
 <ul>
 <li>The SFSA option byte can only be set by the CPU2. The user cannot modify that value.</li>

	<p>This driver is composed of the descriptions of the registers under “Include” directory.</p>
	<p>Various template file are provided to easily build an application. They can be adapted to fit applications requirements.</p>
	<ul>
	<li>Templates/system_stm32wbxx.c contains the initialization code referred as SystemInit.</li>
	<li>Startup files are provided as example for IAR©, KEIL© and STM32CubeIDE©.</li>
	<li>Linker files are provided as example for IAR©, KEIL© and STM32CubeIDE©.</li>
	</ul>
	<h1 id="specific-consideration-for-available-flash-size-inside-linker-file">Specific consideration for available FLASH size inside linker file</h1>
	<p>The available flash size depends on the wireless binary used inside the STM32WB device.</p>
	<p>The linker files templates for IAR, KEIL and GCC provide example of implementation which can be tuned.</p>
	<p>You can refer to the below chapters to optimize the usage of the flash on your device.</p>
	<h2 id="stm32wb55xx-stm32wb50xx-and-stm32wb5m">STM32WB55xx, STM32WB50xx and STM32WB5M</h2>
	<p>The default linker file provided in “/Drivers/CMSIS/Device/ST/STM32WBxx/Source/Templates” allows the application to use 512KB of flash.</p>
	<p>The maximum flash memory that can be used by the application is up to the Secure Flash Start Address (SFSA) that can be read from the option byte.</p>
	<p>The __ICFEDIT_region_ROM_end__ in the linker can be modified with a value up to : (0x08000000 + (SFSA << 12)) - 1.</p>
	<p>Example:</p>
	<ul>
	<li>When the SFSA option byte is set to 0xA0, the maximum value to be used for __ICFEDIT_region_ROM_end is 0x0809FFFF which is 640KB of flash.</li>
	</ul>
	<p>Note:</p>
	<ul>
	<li>The SFSA option byte can only be set by the CPU2. The user cannot modify that value.</li>

	<p>The default linker file provided in "/Drivers/CMSIS/Device/ST/STM32WBxx/Source/Templates allows the application to use 120KB of flash.</p>
	<p>The maximum flash memory that can be used by the application is up to the Secure Flash Start Address (SFSA) that can be read from the option byte.</p>
	<p>The __ICFEDIT_region_ROM_end__ in the linker can be modified with a value up to : (0x08000000 + (SFSA << 12)) - 1.</p>
	<p>Example:</p>
	<ul>
	<li>When the SFSA option byte is set to 0x32, the maximum value to be used for __ICFEDIT_region_ROM_end is 0x08031FFF – which is 200KB of flash</li>
	</ul>
	<p>Note:</p>
	<ul>
	<li>The SFSA option byte can only be set by the CPU2. The user cannot modify that value.</li>

	<p>The default linker file provided in "/Drivers/CMSIS/Device/ST/STM32WBxx/Source/Templates allows the application to use 110KB of flash.</p>
	<p>The maximum flash memory that can be used by the application is up to the Secure Flash Start Address (SFSA) that can be read from the option byte.</p>
	<p>The __ICFEDIT_region_ROM_end__ in the linker can be modified with a value up to : (0x08000000 + (SFSA << 11)) - 1 considering minimum CPU secure area size is one sector (2kBytes).</p>
	<p>Example:</p>
	<ul>
	<li>When the SFSA option byte is set to 0x37, the maximum value to be used for __ICFEDIT_region_ROM_end is 0x0801B800 – which is 110kB of flash</li>
