3.1 Firmware Description

The TUSB5461-Q1 EVM uses the TPS65987 power delivery (PD) controller to manage the Type-C VBUS, handle configuration channel negotiation, and to set the CTL0/CTL1/FLIP pins on the TUSB5461-Q1. The TPS65987 can be configured by loading firmware through the SPI programming header located on the side of the EVM. This evaluation module comes with pre-loaded firmware, but if a certain behavior is desired, custom firmware can be loaded to the PD controller as well. For details on creating a custom firmware file, see the TPS6598X-CONFIG page on TI.com.
