DESCRIPTION
|
|
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 _IsrWrapper() to all the IRQ entries in the vector table.
|
|
|
|
b) When the BSP is written so that device ISRs are installed directly in the
|
|
vector table, they are enumerated here.
