CONFIG_GEN_IRQ_START_VECTOR

(No prompt – not directly user assignable.)

Type: int

Help

On some architectures, part of the vector table may be reserved for system exceptions and is declared separately from the tables created by gen_isr_tables.py. When creating these tables, this value will be subtracted from CONFIG_NUM_IRQS to properly size them. This is a hidden option which needs to be set per architecture and left alone.
