For PT2607 version, when transmission enable signals from Pins -- D12 to D15 -- are received, PT2607 begins a three-word transmission cycle. This three-word transmission cycle will continue as long as the transmission enable (D12 to D15) is held “HIGH”. When D12 to D15 goes to “LOW” (that is, the transmission enable become “LOW”), the encoder output completes its final three-word transmission cycle and then stops. Please refer to the diagram below.
