There are multiple test points (30) on the board that can be used to either measure the associated trace or apply external signals to for testing purposes. Table 3-5 shows the test points for the eight generic U1 connections. There are two test points per pin of the IC, which are colored blue. The test points with format TPX are farther from the U1 device than test points with the format TP1XX.
