This function is used to retain the position data synchronously with the three-phase waveform
output.There are three position-data input pins for U, V, and W phases.
A trigger to retain the position data (hereafter, this trigger is referred to as "retain trigger") can be selected
by the PDRT bit in the PDRF register. This bit selects the retain trigger to be the falling edge of each
positive phase, or the rising edge of each positive phase.

Figure 12.35 shows a usage example of the position-data-retain function (U phase) when the retain
trigger is selected as the falling edge of the positive signal.

(1) At the falling edge of the U-phase waveform ouput, the state at pin IDU is transferred to the PDRU
(2) Until the next falling edge of the Uphase waveform output,the above value is retained.
