|--------------|--------------------|-----------------------|
| 0x0 | CHCFG0 | CHCFG3 |
|--------------|--------------------|-----------------------|
| 0x1 | CHCFG1 | CHCFG2 |
|--------------|--------------------|-----------------------|
| 0x2 | CHCFG2 | CHCFG1 |
|--------------|--------------------|-----------------------|
| 0x3 | CHCFG3 | CHCFG0 |
|--------------|--------------------|-----------------------|
| ... | ...... | ...... |
|--------------|--------------------|-----------------------|
| 0xC | CHCFG12 | CHCFG15 |
|--------------|--------------------|-----------------------|
| 0xD | CHCFG13 | CHCFG14 |
