## Function Syntax

```plaintext theme={null}
void SCC_CM_Amp_Map_Req(byte RunId[], byte SourceMac[], dword AmLen, byte AmData[])
```

## Description

The callback is called as soon as a `CM_Amp_Map.Req` message is received.

## Parameters

* **RunId**: 8-byte long run ID.
* **SourceMac**: MAC address of sender.
* **AmLen**: Length of the AmData array.
* **AmData**: Power spectral density difference values as defined by the specification. **Note**: Because the PSD is defined in values of 4 bit, only the lower half of each byte is considered.
