PRODUCTION DATA.
To write to a continuous block of registers, the I2C master has to provide an I2C command as illustrated in Figure 53. The register address is the address of the first register in the block which needs to be written. The I2C master has to provide data for registers in subsequent I2C frames in an ascending order of register addresses. Writing data to addresses which do not exist in the Register Map of the device has no effect. The opcode for writing a continuous block of registers is listed in Table 4. If the data provided by the I2C master exceeds the address space of the device, the device neglects the data beyond the address space. To end the register write command, the master has to provide a STOP or a RESTART condition in the I2C frame.
