==== Chunk Type Details ====
Each chunk type has a header with the following details. The header is typically followed by chunk data + a 4 byte CRC.

| chunkID | Signature for each header type, always 0xAD |
| chunkType | ID for chunk type | 
| major version | Major version number |
| minor version | Minor version number |
| headerSizeBytes | Header Size, always 20 |
| chunkSizeBytes | Size of chunk data |
| nextChunkHeader | Address of next chunk header |
| chunkHeaderCRC | CRC of previous 16 bytes |

=== NVM Header ===
The NVM header always starts at address 0x0. 

| **Content** | **Size (bytes)** | **Value** | **Description** | 
| chunkID | 1            | 0xAD | |
| chunkType | 1          | 0x3D | |
| major version | 1      | 0x## | |
| minor version| 1       | 0x## | |
| headerSizeBytes | 4    | 20   | |
| chunkSizeBytes | 4     | 0x00 | Always 0 |
| nextChunkHeader | 4    | 0x14 | |
| chunkHeaderCRC | 4     | CRC | CRC of previous 16 bytes |

=== CCB ===
| **Content** | **Size (bytes)** | **Value** | **Description** | 
| chunkID | 1            | 0xAD | |
| chunkType | 1          | 0x01 | |
| major version | 1      | 0x## | |
| minor version| 1       | 0x## | |
| headerSizeBytes | 4    | 20   | |
| chunkSizeBytes | 4     | 0x## | Size of CCB |
| nextChunkHeader | 4    | 0x## | Location of next header|
| chunkHeaderCRC | 4     | CRC | CRC of previous 16 bytes |
| CCB Data       | chunkSizeBytes | DATA | |
| CCB Data CRC   | 4 bytes | CRC | CRC of CCB data |
