In addition to the resistances recommended in the I2C (I2C), Debug Control (DEBUG_CTL), and Single-Wire De-bugger (SWD) Resistors section, additional series resistors are used for debugging. The two I2C channels allow a designer to check the system state through the Host Interface Specification. By attaching 0-Ω series resistors between the I 2C master and the TPS65982 and additionally adding 0-Ω series resistors between the TPS65982 and test points, a multi- master scenario can be avoided. This allows breaking the connection between the I2C channels and the system to allow I2C access to the TPS65982 from an external tool. A header is used to allow for connections without soldering; however, SMT test pads can be used to provide a place to solder blue-wires for testing. Exposing the SWD_DATA and SWD_CLK pins will allow for more advanced debugging if needed. A header or SMT test point is also used for the SWD_DATA and SWD_CLK pins. 10.2.2.3 Application Curves Figure 83. DC Barrel Jack and Type-C PD Charging Hand-Off Figure 84.
