The period of arbitration lost detection When detecting the difference between a data on CEC bus and a send data by 32 kHz sampling, identify an arbitration lost occurs. 3.1 Original The period of arbitration lost detection is as follows: - From the start of the “0” output until the end of the “1” output period. Figure 3-1 Arbitration Lost Detection Period (Current) Sampling at about 32kHz cycle “0” output period “1” output period Next bit Detection period 3.2 Modification The period of arbitration lost detection is changed as follows: - During the “1” out put from 300µs(10 clock) after the bus data rises to high Figure 3-2 Arbitration Lost Detection Period (Modified) 300us Sampling at about 32kHz cycle Detect period “0” output period Next bit “1” output period mcu_CI706-00015-1v1-E December 17, 2013 3 C u s t o m e r I n f o r m a t i o n 4.
