Output Mechanisms
5.1
Introduction
The MPR03X has three outputs: the touch status, values from the second level filter (Section 8.3), and the calibrated baseline
values. The application can either use the touch status or a combination of second level filter data with the baseline data to
determine when a touch occurs.
5.2
Touch Status
Each Electrode has an associated single bit that denotes whether or not the pad is currently touched. This output is generated
using the touch threshold and release threshold registers to determine when a pad is considered touched or untouched.
Configuration of this system is discussed in Section 9.
5.2.1
The Touch Pad Status Register is a read only register for determining the current status of the touch pad. The I2C slave address
of the Touch Pad Status Register is 0x00.

OCF
Over Current Flag – The Over Current Flag shows when too much current is on the REXT
pin. If it is set all other status flags and registers are cleared and the device is set to Stop
mode. When OCF is set, the MPR03X cannot be put back into a Run mode.
0 – Current is within limits.
1 – Current is above limits. Writing a 1 to this field will clear the OCF.
2
E2S
Electrode 2 Status – The Electrode 2 Status bit shows touched or not touched.
0 – Not Touched
1 – Touched
1
E1S
Electrode 1 Status – The Electrode 1 Status bit shows touched or not touched.
0 – Not Touched
1 – Touched
0
E0S
Electrode 0 Status – The Electrode 0 Status bit shows touched or not touched.
0 – Not Touched
1 – Touched
