| Before the above tick-count field is updated, that value is copied into this field. Therefore, this contains the tick-count for the previous time that entry index0 in the below array was updated by IR module.

| 0x24
| 0x80
| Array of 8 entries, where each entry(see below) is 0x10-bytes.

IR module first updates index0, then index1, and so on. When updating the array when the index is already 7, the index is reset to 0.
