/**
 * @brief IRQ part of vector table for Quark SE Sensor Subsystem
 *
 * 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.
