1.3 Read Register and Write Register Functions

When using the BQ79600 UART sample code, ReadReg function is used to generate a read command and receive a response, and WriteReg function is used to generate a write command. When using the BQ79600 SPI sample code, the names of these functions are SpiReadReg and SpiWriteReg, respectively. These act as the primary communication wrapper functions between the TMS570 LaunchPad and the BQ79600-Q1. The CRC is automatically calculated and appended by these functions.
