- The first ppem value in the range
- last
- The last ppem value in the range
- val
- This is an array of deltas corresponding to each ppem in the range between first and last inclusive.
- fmt
- This is the fmt used (log2 of number bits per value) when the device table was read. It is recalculated on output.
