I2C bus specification
STA333BW
5.4.4
Random address multi-byte read
The multi-byte read modes could start from any internal address. Sequential data bytes are
read from sequential addresses within the STA333BW. The master acknowledges each
data byte read and then generates a STOP condition terminating the transfer.
