9.4 Data write mode
9.5 Data read mode
The data write mode is explained in the signal diagram of
device, 4 bytes must be sent (see
It should be noted that each time a new destination register address needs to be written,
the device address must be sent again.
Table 14:
To read data from the device, a prepare read must first be done and then data read. The
data read mode is explained in the signal diagram of
For reading data from a device, the following 6 bytes are involved (see
