CONFIG_2ND_LVL_ISR_TBL_OFFSET

Offset in _sw_isr_table for level 2 interrupts

Type: int

Help

This is the offset in _sw_isr_table, the generated ISR handler table, where storage for 2nd level interrupt ISRs begins. This is typically allocated after ISRs for level 1 interrupts.

      This is the offset in _sw_isr_table, the generated ISR handler table,
      where storage for 2nd level interrupt ISRs begins. This is
      typically allocated after ISRs for level 1 interrupts.
