Functional Description

Operation

The 312 series of encoders begin with a four (HT6010) or a one (HT6012/HT6014) word transmission cycle upon receipt

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.
