Touch Acquisition Sample Period Register
The Touch Acquisition Sample Period Register is used to determine the electrode scan period of the system. The I2C slave
address of the Touch Acquisition Sample Period Register is 0x0F.

TPSE
Touch Pad Sounder Enable – The Touch Pad Sounder Enable bit controls if data
is sent to the sounder.
0 Disable – Click Feedback Off
1 Enable – Click Feedback On
5
BKA
Best Key Algorithm - The Best Key Algorithm, when enabled the Maximum Number
of Touches register is ignored and the algorithm reports the single best key based
upon the BKA algorithm and all electrodes that are decoding a touch.
0 BKA Disabled
1 BKA Enabled
4
ACE
Auto Calibration Enable – The Auto Calibration Enable bit enables or disables the
auto calibration function.
0 Disable
1 Enable
3
TPRBE
Touch Pad Release Buffer Enable – The Touch Pad Release Buffer Enable bit
determines whether or not data is logged in the FIFO when the touch pad
transitions from a touched to untouched state.
0 Disable – No Release Data Logged
1 Enable – Release Data Logged
2
TPTBE
Touch Pad Touch Buffer Enable – The Touch Pad 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
TPE
Touch Pad Enable – The Touch Pad 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
