RSE
Rotary Sounder Enable – The Rotary Sounder Enable bit controls if data is sent to
the sounder.
0 Disable – Click Feedback Off
1 Enable – Click Feedback On

ACE
Auto Calibration Enable – The Auto Calibration Enable bit enables or disables the
auto calibration function.
0 Disable
1 Enable

RRBE
Rotary Release Buffer Enable – The Rotary Release Buffer Enable bit determines
whether or not data is logged in the FIFO when the rotary transitions from a touched
to untouched state.
0 Disable – No Release Data Logged
1 Enable – Release Data Logged
2
RTBE
Rotary Touch Buffer Enable – The Rotary Touch Buffer Enable bit determines
whether or not data is logged in the FIFO any time a button is pressed.
0 Disable – Touches are not logged
1 Enable – Touches are logged
0
RE
Rotary Enable – The Rotary Enable bit enables or disables the touch sensor. When
disabled, no touches are detected.
0 Disable – Touches not detected
1 Enable – Touches detected

TASP
Touch Acquisition Sample Period – The Touch Acquisition Sample Period Field
selects or reports the multiplication factor that is used to determine how often
electrodes are scanned. The resulting factor must be in the range 1 to 32. If the
value is outside of this range the TASP will be set to 00011111.
00000000 Encoding 0 – Sets the TASP multiplication factor to 1
~
00011111 Encoding 31 – Sets the TASP multiplication factor to 32.
