The register address is the address of the register which must be read. The opcode for register read command is listed in Table 4. Figure 49. Setting Register Address for Reading Registers After this, the I2C master has to provide another I2C frame containing the device address and read bit as illustrated in Figure 50. After this frame, the device provides register data. If the host provides more clocks, the device provides same register data. To end the register read command, the master has to provide a STOP or a RESTART condition in the I2C frame. |
