RS = Repeated start condition

SA = Slave Acknowledgement
MA = Master Acknowledgement
AA = Device address, 10 bits
CASE 4: I2C 16 bit read (any number of bytes can be read, length is determined by end condition generated by master).
Automatic register address changing depends on selected start address in I2C_RD_SEL (noted by addr and addr_x on the figure).
CASE 1: I2C 8 bit write
CASE 2: I2C 16 bit write (any number of bytes can be written, length is determined by end condition generated by master)
CASE 3: I2C 8 bit read, read address for SCA3000 series register should be written to I2C_RD_SEL register
