Run1 Mode
In Run1 Mode, the MPR03X monitors 1, 2, or 3 electrodes which are connected to a user defined array of touch pads. When only
1 or 2 electrodes are selected, the IRQ/ELE2 pin is automatically configured as an open drain interrupt output.
When 3 electrodes are selected in Run1 Mode, the IRQ/ELE2 pin becomes the third electrode input, ELE2 (Figure 14).
Figure 14. Electrode/Pad Connections in Run Mode
4.4
Run2 Mode
In Run2 Mode, all enabled electrodes act as a single electrode by internally connecting the electrode pins together. The entire
surface of all the touch pads is used as a single pad, increasing the total area of the conductor.
When 2 electrodes are selected in Run2 Mode, the IRQ/ELE2 pin is automatically configured as an open drain interrupt output.
When 3 electrodes are selected, the IRQ/ELE2 pin becomes the third electrode input, ELE2 (Figure 15).

The Electrode Configuration Register manages the configuration of the Electrode outputs in addition to the mode of the part. The
address of the Electrode Configuration Register is 0x44.
