## Name

ilsel_enable — Enable an ILSEL set.

## Synopsis

`int ilsel_enable (` | ilsel_source_t set`)`;

## Arguments

`set`

  ILSEL source (see ilsel_source_t enum in include/asm-sh/ilsel.h).

## Description

Enables a given non-aliased ILSEL source (<= ILSEL_KEY) at the highest available interrupt level. Callers should take care to order callsites noting descending interrupt levels. Aliasing FPGA and external board IRQs need to use `ilsel_enable_fixed`.

The return value is an IRQ number that can later be taken down with `ilsel_disable`.
