ACD: Judging count (read/write enabled only in setup mode)
CHEN: Measurement enable for each channel (read/write enabled only in setup mode)
TCAL: Teaching measurement count (read/write enabled only in setup mode)
TOG: Toggle action (read/write enabled only in setup mode)
Set the output polarity logic of On/Off output signal.
1:High Active (OUTx terminal is HIGH when touched)
0:Low Active (OUTx terminal is LOW when touched)
Only the lower-order 8 bits are valid. If the other bits are written to, they are ignored.
Enable / Disbale measurement per channel
1: measurement executed, 0: not executed
Only the lower-order 4 bits are valid. If the other bits are written to, they are ignored.
Defines the termination of the teaching algorithm if not 3 touch events per channel were found with this
time.
Only the lower-order 8 bits are valid. If the other bits are written to, they are ignored.
Selects momentary or latching output mode. This output takes effect on the signals output from OUT0 -
7 and BDATA command data.
1: Toggle mode off (momentary action: turned on only during a touch event)
0: Toggle mode on (alternate action: turned on with the first touch event and off with the next touch
event)
Only the lower-order 8 bits are valid. If the other bits are written to, they are ignored.
After ACD value + 1 consecutive measurements a touch event(or no-touch event) is judged and the
output state is changed. This takes effect on the output signals from OUT0 - 7 and BDATA command
data.
For example, with ACD = 2, after three consecutive measurements are judged as a touch event(or no-
touch event), the output state changes.
