8.5.1.3.4 Communication Diagnostics

The BQ79606A-Q1 provides comprehensive debugging information for the communication interface. Each communication interface (UART, COML, and COMH) has fault registers to assist with debug during development. The COMM_*_FAULT registers indicate faults that occur at the interface level. Faults indicated here inform the host that the data received is likely wrong and should not be trusted. The COMM_*_RR_FAULT registers indicate faults that occur while receiving a response frame. The COMM_*_RC_FAULT registers indicate faults that occur while receiving a command frame. The COMM_*_TR_FAULT registers indicate faults that occur while transmitting. Additionally, the TONE_FAULT register indicates faults related to the FAULT interface. See the individual register description for specifics on the individual fault conditions. Frame counters are provided for transmitted, received, and discarded frames for each bus.
