Position-data-retain Function Control Register
This bit is used to retain the input level at pin IDW.
This bit is used to retain the input level at pin IDV.
This bit is used to retain the input level at pin IDU.
This bit is used to select the trigger polarity to retain the position data.
When this bit is set to "0", the rising edge of each positive phase selected.
When this bit is set to "1", the falling edge of each pocitive phase selected.
