;* Description : STM32G050xx devices vector table for EWARM toolchain.
|
||||
;* 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-M0+ processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

;* Description : STM32G051xx 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 CortexM0 processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

|

;* Description : STM32G051xx devices vector table for EWARM toolchain.
|
||||
;* 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-M0+ processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

;* Description : STM32G061xx 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 CortexM0 processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

|

;* Description : STM32G061xx devices vector table for EWARM toolchain.
|
||||
;* 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-M0+ processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

;* Description : STM32G0b0xx 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 CortexM0 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-M0+ processor is in Thread mode,
|

* priority is Privileged, and the Stack is set to Main.

|

;* Description : STM32G0B0xx devices vector table for EWARM toolchain.
|
||||
;* 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-M0+ processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

; The vector table is normally located at address 0.

; When debugging in RAM, it can be located in RAM, aligned to at least 2^6.

; The name "__vector_table" has special meaning for C-SPY:

|

;* Description : STM32G0B1xx devices vector table for EWARM toolchain.
|
||||
;* 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-M0+ processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.

|

;* Description : STM32G0C1xx devices vector table for EWARM toolchain.
|
||||
;* 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-M0+ processor is in Thread mode,
|
||||
;* priority is Privileged, and the Stack is set to Main.
