|
||||||
|
;* Description : STM32L432xx Ultra Low Power devices vector table for MDK-ARM toolchain.
|
||||||
|
;* This module performs:
|
||||||
|
;* - Set the initial SP
|
||||||
|
;* - Set the initial PC == Reset_Handler
|
||||||
|
;* - Set the vector table entries with the exceptions ISR address
|
||||||
|
;* - Branches to __main in the C library (which eventually
|
||||||
|
;* calls main()).
|
||||||
|
;* After Reset the Cortex-M4 processor is in Thread mode,
|
||||||
|
;* priority is Privileged, and the Stack is set to Main.

|

|
;* This module performs:
|

|
;* - Set the initial SP
|

|
;* - Set the initial PC == Reset_Handler
|

|
;* - Set the vector table entries with the exceptions ISR address
|
||||||
|
;* - Branches to __main in the C library (which eventually
|
||||||
|
;* calls main()).
|
||||||
|
;* After Reset the Cortex-M4 processor is in Thread mode,
|
||||||
|
;* priority is Privileged, and the Stack is set to Main.

|
;* Description : STM32L432xx Ultra Low Power Devices vector
|
||||||
|
;* This module performs:
|
||||||
|
;* - Set the initial SP
|
||||||
|
;* - Set the initial PC == _iar_program_start,
|
||||||
|
;* - Set the vector table entries with the exceptions ISR
|
||||||
|
;* address.
|
||||||
|
;* - Branches to main in the C library (which eventually
|
||||||
|
;* calls main()).
|
||||||
|
;* After Reset the Cortex-M4 processor is in Thread mode,
|
||||||
|
;* priority is Privileged, and the Stack is set to Main.

|

|
* This file provides two functions and one global variable to be called from
|
||||||
|
* user application:
|
||||||
|
* - SystemInit(): This function is called at startup just after reset and
|
||||||
|
* before branch to main program. This call is made inside
|
||||||
|
* the "startup_stm32l4xx.s" file.
|
||||||
|
*
|
||||||
|
* - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
|
||||||
|
* by the user application to setup the SysTick
|
||||||
|
* timer or configure other parameters.
|
||||||
|
*
|
||||||
|
* - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
|
||||||
|
* be called whenever the core clock is changed
|
||||||
|
* during program execution.
|
||||||
|
*
|
||||||
|
* After each device reset the MSI (4 MHz) is used as system clock source.
|
||||||
|
* Then SystemInit() function is called, in "startup_stm32l4xx.s" file, to
|
||||||
|
* configure the system clock before to branch to main program.
|
||||||
|
*
|
||||||
|
* This file configures the system clock as follows:
|
||||||
|
*=============================================================================
|
||||||
|
* System clock source | 1- PLL_HSE_EXTC | 3- PLL_HSI
|
||||||
|
* | (external 8 MHz clock) | (internal 16 MHz)
|
||||||
|
* | 2- PLL_HSE_XTAL | or PLL_MSI
|
||||||
|
* | (external 8 MHz xtal) | (internal 4 MHz)
|
||||||
|
*-----------------------------------------------------------------------------
|
||||||
|
* SYSCLK(MHz) | 48 | 80
|
||||||

*-----------------------------------------------------------------------------
|

|
* AHBCLK (MHz) | 48 | 80
|

|
*-----------------------------------------------------------------------------
|
||||||
|
* APB1CLK (MHz) | 48 | 80
|
||||||
|

|
||||||
|
* APB2CLK (MHz) | 48 | 80
|
||||||
|
*-----------------------------------------------------------------------------
|
