Serial Interface Reference programming interface ADJD-S313 2-wire serial bus. consists serial clock (SCL) serial data (SDA) line. line bi-directional ADJD-S313 must connected through pull-up resistor positive power supply. When free, both lines HIGH. 2-wire serial ADJD-S313 requires device master while other devices must slaves. master device that initiates data transfer bus, generates clock signal terminates data transfer while device addressed master called slave. Slaves identified unique device addresses. Both master slave transmitter receiver master controls direction data transfer. transmitter device that sends data receiver device that receives data from bus. ADJD-S313 serial interface always operates slave transceiver with data transfer rate 100kbit/s.
START/STOP Condition
master initiates terminates serial data transfers. begin serial data transfer, master must send unique signal called START condition. This defined HIGH transition line while HIGH. master terminates serial data transfer sending another unique signal called STOP condition. This defined HIGH transition line while HIGH. considered busy after START condition. will considered free certain time after STOP condition. stays busy repeated START (Sr) sent instead STOP condition. START repeated START conditions functionally identical.
Data Transfer
master initiates data transfer after START condition. Data transferred bits with master generating clock pulse each sent. data valid, data line must stable during HIGH period clock line. Only during period clock line data line change state either HIGH LOW.

Figure shows example master implementation clock line data line synchronized. complete data transfer 8-bits long 1-byte. Each byte sent most significant (MSB) first followed acknowledge acknowledge bit. Each data transfer send unlimited number bytes (depending data format).

Addressing Each slave device serial needs have unique address. This first byte that sent master-transmitter after START condition. address defined first seven bits first byte. eighth least significant (LSB) determines direction data transfer. `one' first byte indicates that master will read data from addressed slave (masterreceiver slave-transmitter). `zero' this position indicates that master will write data addressed slave (master-transmitter slave-receiver). device whose address matches address sent master will respond with acknowledge first byte itself slavetransmitter slave-receiver depending first byte. slave address ADJD-S313 0x58 (7-bits).

Figure Slave Addressing
Data format ADJD-S313 uses register-based programming architecture. Each register unique address controls specific function inside chip. write register, master first generates START condition. Then sends slave address device wants communicate with. least significant (LSB) slave address must indicate that master wants write slave. addressed device will then acknowledge master. master writes register address wants access waits slave acknowledge. master then writes register data. Once slave acknowledges, master generates STOP condition data transfer.
read from register, master first generates START condition. Then sends slave address device wants communicate with. least significant (LSB) slave address must indicate that master wants write slave. addressed device will then acknowledge master. master writes register address wants access waits slave acknowledge. master then generates repeated START condition resends slave address sent previously. least significant (LSB) slave address must indicate that master wants read from slave. addressed device will then acknowledge master. master reads register data sent slave sends acknowledge signal stop reading. master then generates STOP condition data transfer.
