DA9130 High-Performance, 10 A, Dual-Phase DC-DC Converter
When the host reads data from a register it first has to write to DA9130 with the target register address and then read from DA9130 with a repeated START, or alternatively a second START, condition. After receiving the data, the host sends no acknowledge (A*) and terminates the transmission with a STOP condition, see Figure 11.
