LV5207LP no.a0943-8/14 i 2 c bus transmission method start and stop conditions in the i 2 c bus, sda must basically be kept in the constant state while scl is "h" as shown below during data transfer. when data transfer is not made, both scl and sda are in the "h" state. when scl = sda = "h", change of sda from "h" to "l" enables the start conditions to start access. when scl is "h", change of sda from "l" to "h" enables the stop conditions to stop access. data transfer and acknowledgement response after establishment of start conditions, data tr ansfer is made by one byte (8 bits). data transfer enables continuous tr ansfer of any number of bytes. each time the 8-bit data is transferred, the ack signal is sent from the receive side to the send side. the ack signal is issued when sda on the send side is re leased and sda on the receive side is set "l" immediately after fall of the clock pulse at the scl eighth bit of data transfer to "l". when the next 1-byte transfer is left in the receive stat e after transmission of the ack signal from the receive side, the receive side releases sda at fall of the scl ninth clock. in the i 2 c bus, there is no ce signal. instead , 7-bit slave address is assigned to each device and the first byte of transfer is assigned to the command (r/w) representing the 7-bit slave address and subsequent transfer direction. note that only write is valid in LV5207LP. the 7-bit address is transferred sequentially from msb and the eight bit is "l" representing write. in LV5207LP, the slave addre ss is specified as (1110101). ts2 th2 scl sda m s b l s b a c k l s b a c k m s b m s b l s b a c k w 1 scl sda (write) start slave address register address data stop 110101 000 1 000 0 000 0 100 1 th1 ts3 scl sda start condition stop condition
