Setting of data presentation
‘1’ to display 1 byte position data in the first byte of RE1_POS and RE2_POS continuously. The
old data will be overwritten. In this mode, when touch is detected in the slider, interrupt is issued
and host can read the data in its own rate. Only position data is available (8 bits), movement
and time-stamp data are not available.
‘0’ to enable data-buffering. Position, movement and time-stamp are available.
