| `uint32` | `u32ItemBitmap` | 割り込みパラメータ |

## 戻り値

なし。

## サンプル

```c
void cbToCoNet_vHwEvent(Uint32 u32DeviceId, uint32 u32ItemBitmap) {
    Switch (u32DeviceId) {
    case E_AHI_DEVICE_SYSCTRL: // DIO etc
        if (u32ItemBitmap & (1UL << 12) {
            ; // interrupt on DIO12
        }
        break;
    case E_AHI_DEVICE_TICK_TIMER: // TickTimer
        vPortSet_TrueAsLo(18, u32TickCount_ms & 0x400); // blink LED every sec.
        break;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://sdk.twelite.info/twelite-net-api-ref/krubakku/cbtoconet_vhwevent.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
