The DATA and CLK make up the BUS Interface. It should be noted that the pullup resistors must be connected to the positive supply voltage. Data Validity A data on the DATA Line is considered valid and stable only when the CLK Signal is in HIGH State. The HIGH and LOW State of the DATA Line can only change when the CLK signal is LOW. Please refer to the figure below. Start and Stop Conditions A Start Condition is activated when 1) the CLK is set to HIGH and 2) DATA shifts from HIGH to LOW State. The Stop Condition is activated when 1) CLK is set to HIGH and 2) DATA shifts from LOW to HIGH State. Please refer to the timing diagram below.

Each byte must be followed by an Acknowledge Bit. The MSB is transmitted first. Acknowledge During the Acknowledge Clock Pulse, the master (µP) puts a resistive HIGH level on the DATA Line. The peripheral (audio processor) that acknowledges has to pull-down (LOW) the DATA line during the Acknowledge Clock Pulse so that the DATA Line is in a Stable Low State during this Clock Pulse. Please refer to the diagram below. The audio processor that has been addressed has to generate an acknowledge after receiving each byte, otherwise, the DATA Line will remain at the High Level during the ninth (9th) Clock Pulse. In this case, the master transmitter can generate the STOP Information in order to abort the transfer. Transmission without Acknowledge If you want to avoid the acknowledge detection of the audio processor, a simpler µP transmission may be used. Wait one clock and do not check the slave acknowledge of this same clock then send the new data. If you use this approach, there are greater chances of faulty operation as well as decrease in noise immunity. Interface Protocol The interface protocol consists of the following: • A Start Condition • A Chip Address Byte including the PT2313 address. The 8th Bit of the Byte must be “0”. PT2313 must always acknowledge the end of each transmitted byte. PT2313 v 1 Page 5 Written Feb. 1997 PTC Princeton Technology Corp.
