  * @brief The key diversification algorithm uses 6-bit bytes.
  * This implementation uses 64 bit uint to pack seven of them into one
  * variable. When they are there, they are placed as follows:
- * XXXX XXXX N0 .... N7, occupying the lsat 48 bits.
+ * XXXX XXXX N0 .... N7, occupying the last 48 bits.

  * This function picks out one from such a collection
