NOTES:
1. All timing measurements are defined at the point of signal crossing VDD / 2.
2. These parameters are periodically sampled and are not 100% tested.
3. The 24k+20% resistors are configured as 4 resistors in parallel which would provide a measured value between VREFH and VREFL of 6k+20%. The individual 24k
resistors are not measurable but guaranteed by design and verification of the 6k+20% value.
