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## | |
