* @brief IRQ part of vector table
|
|
*
|
|
* This file contains the IRQ part of the vector table. It is meant to be used
|
|
* for one of two cases:
|
|
*
|
|
* a) When software-managed ISRs (SW_ISR_TABLE) is enabled, and in that case it
|
|
* binds _isr_wrapper() to all the IRQ entries in the vector table.
|
|
*
|
|
* b) When the platform is written so that device ISRs are installed directly in
|
|
* the vector table, they are enumerated here.
