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 retain-trigger polarity select bit(bit 3 of the position-data-retain function control register, at address
034E

Figure 12.3.1.1.1 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 U-
phase position data retain bit ( bit2 at address 034E
(2) Until the next falling edge of the Uphase waveform output,the above value is retained.
