Poor Schematic image for reference design

Hello TI,

                We are trying to understand the program and schematic of Heart Rate Monitor Wrist Watch with your reference design so that we could make our own in future. The schematic in pdf file http://www.ti.com/lit/df/tidr098/tidr098.pdf is illegible and we couldn't actually understand the labels on many pins of microcontroller. If possible, please provide us the better quality image so that we can learn from your reference design.
