LV5234V no.a1936-10/23 i 2 c bus transfer method start and stop conditions during data transfer operation using the i 2 c bus, sda must basically be kept in constant state while scl is ?h? as shown below. when data is not being transferred, both scl and sda are set in the ?h? state. when scl=sda is ?h,? the start conditio n is established when sda is changed from ?h? to ?l,? and access is started. when scl is ?h,? the stop condition is established when sda is changed from ?l? to ?h,? and access is ended. data transfer and acknowledgement response after the start condition has been established, the data is transferred one byte (8 bits) at a time. any number of bytes of data can be transferred continuously. 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 released and sda on the receive side is set to ?l? immediately after fall of the clock pulse at the scl eighth b it of data transfer to ?l.? when the next 1-byte transfer is left in the receive state after sending the ack signal from the receive side, the receive side releases sda at the fall of the scl ninth clock. in the i 2 c bus, there is no ce signal. in its place, a 7-bit slave address is assi gned to each device, and the first byte of transfer is assigned to the command (r/w) representing the 7-bit address and subseq uent transfer direction. note that only write is valid in this ic. the 7-bit address is transferre d sequentially starting with msb, and the eighth bit is set to ?l? which indicates a write. ts2 th2 scl sda th1 scl sda ts3 start condition stop condition scl sda start m s b l s b w a c k m s b l s b a c k m s b l s b a c k stop slave address register address data
