1.2-4 Data transmission write format in the RS5C372A/B

Although the I2C bus standard defines a transmission format for the slave address allocated for each IC,

transmission method of address information in IC is not defined. The RS5C372A/B transmit data the internal

address pointer (4bit) and the transmission format register (4bit) at the 1byte next to one which transmitted a

slave address and a write command. For write operation only one transmission format is available and (0000) is

set to the transmission format register. The 3byte transmits data to the address specified by the internal address

pointer written to the 2byte. Internal address pointer settings are automatically incremented for 4byte and after.

Note that when the internal address pointer is Fh, it will change to 0h on transmitting the next byte.
