 <h1 id="purpose">Purpose</h1>
 <p>This driver provides the CMSIS device for the STM32L5 products. This covers STM32L552xx/STM32L5622x devices.</p>
 <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>Include/Templates/partition_stm32l552xx.h and partition_stm32l562xx.h contain a default Secure Attribute Unit (SAU) set up from SystemInit() for secure application when the security is enabled (TZEN=1).</li>
 <li>Source/Templates/system_stm32l5xx.c contains the initialization code referred as SystemInit() when there is no security enabled (TZEN=0).</li>
 <li>Source/Templates/system_stm32l5xx_s.c contains the initialization code referred as SystemInit() for secure application when the security is enabled (TZEN=1).</li>
 <li>Source/Templates/system_stm32l5xx_ns.c contains the initialization code referred as SystemInit() for non-secure application when the security is enabled (TZEN=1).</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>

 <p>First official release of STM32L5xx CMSIS Device drivers to support <strong>STM32L552xx and STM32L562xx</strong> devices</p>
 <ul>
 <li>Templates
 <ul>
 <li>When TrustZone security is enabled in the system (Flash option bit TZEN=1), the partition_stm32l552xx.h and partition_stm32l562xx.h are available from \Include\Templates with a default Security Attribute Unit (SAU) configuration:
 <ul>
 <li>SAU region 0: 0x0C03E000-0x0C03FFFF (Secure, Non-Secure Callable)</li>
 <li>SAU region 1: 0x08040000-0x0807FFFF (Non-Secure FLASH Bank2 (256 Kbytes))</li>
 <li>SAU region 2: 0x20018000-0x2003FFFF (Non-Secure RAM (2nd half SRAM1 + SRAM2 (160 Kbytes)))</li>
 <li>SAU region 3: 0x40000000-0x4FFFFFFF (Non-Secure Peripheral mapped memory)</li>
 <li>SAU region 4: 0x60000000-0x9FFFFFFF (Non-Secure external memories)</li>
 <li>SAU region 5: 0x0BF90000-0x0BFA8FFF (Non-Secure System memory)</li>
 </ul></li>
 <li>system_stm32l5xx_s.c and system_stm32l5xx_ns.c for respectively secure application and non-secure application when TrustZone security is enabled (TZEN=1)</li>
 <li>Linker files for 256 and 512 Kbytes Flash device configurations</li>
 </ul></li>
 </ul>
 <h2 id="notes">Notes</h2>
 <p>When TrustZone is enabled in the system (Flash option bit TZEN=1), template device partition_stm32l552xx.h or partition_stm32l562xx.h file must be copied and optionally updated in user application secure project to configure the system (SAU, interrupts, core)</p>
