For Table 2 the Thresh_1 setting is individually dialed in:

The following table, Table 3, shows the results of having turned Vthreshold_1 all the way up and flipping the MSPOLARITY bit to ON. I'm not sure what this means since I was expecting all "ones" this time considering what I had discovered about the front-end circuitry last week.
