Functional Description

Operation

The 3

of a transmission enable (TE for the HT6010 or D8~D11 for the HT6012/HT6014, active low). This cycle will repeat itself

as long as the transmission enable (TE or D8~D11) is held low. Once the transmission enable returns high the encoder

output completes its final cycle and then stops as shown below.

Information Word

An information word is composed of four periods as shown:
