40 / 65 page  Device configuration L6360 40/65 Doc ID 022817 Rev 2 6.4 I2C protocol 6.4.1 Protocol configuration Figure 24. Device initialization Microcontroller initialization: Microcontroller initialization phase. Write mode: The L6360 is configured by the microcontroller through I2C. To configure the device, it is necessary to write its internal registers (see Write modes section). Parity check: L6360 calculates the parity of each received register and stores it in the parity register. After which, it compares it with the parity transmitted together with the data. If the parity check of one or more registers failed, the “parity error bit” in the status register is set and an interrupt is generated by the L6360. The microcontroller can now read the status register and the parity register (current read). So the microcontroller can understand the interrupt cause and which register failed the transmission. If the parity check is ok, the flow goes on (Read modes). Write register failed: The microcontroller can again write the register(s) that failed the check. Read mode: Read status register to monitor if the configuration was good (Read modes). |
