Provides both slave write readback functionality Standard mode 100kbits/s serial bits will read sent clock driver following order Byte Bits Byte Bits Byte Bits This serial protocol designed allow both blocks write read from controller. bytes must accessed sequential order from lowest highest byte. Each byte transferred must followed acknowledge bit. byte transferred without acknowledged will terminate transfer. write read block both begins with master sending slave address write condition (0xD2) read condition (0xD3). Following acknowledge this address byte, Write Mode: Command Byte Byte Count Byte must sent master ignored slave, Read Mode: Byte Count Byte will read master then other Data Byte.
