| 25 | * NOTES |
| 26 | * The BLOCK_COUNTER registers for the ALS300(+) return a figure related to |
| 27 | * the position in the current period, NOT the whole buffer. It is important |
| 28 | * to know which period we are in so we can calculate the correct pointer. |
| 29 | * This is why we always use 2 periods. We can then use a flip-flop variable |
| 30 | * to keep track of what period we are in. |
