Debugging Methods
The TPS65982 has methods of debugging a Type-C and PD system. 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.
