| 40 | Purpose : Exception and interrupt vectors for stm32h723xx devices. |

| 41 | |
|---|
| 42 | Additional information: |
|---|
| 43 | Preprocessor Definitions |
|---|
| 44 | __NO_EXTERNAL_INTERRUPTS |
|---|
| 45 | If defined, |
|---|
| 46 | the vector table will contain only the internal exceptions |
|---|
| 47 | and interrupts. |
|---|
| 48 | __VECTORS_IN_RAM |
|---|
| 49 | If defined, |
|---|
| 50 | an area of RAM, large enough to store the vector table, |
|---|
| 51 | will be reserved. |
|---|
| 52 | |
|---|
| 53 | __OPTIMIZATION_SMALL |
|---|
| 54 | If defined, |
|---|
| 55 | all weak definitions of interrupt handlers will share the |
|---|
| 56 | same implementation. |
|---|
| 57 | If not defined, |
|---|
| 58 | all weak definitions of interrupt handlers will be defined |
|---|
| 59 | with their own implementation. |
