Error
The MPR083 can generate a fault under two conditions; an electrode is shorted to VDD, or an electrode is shorted to VSS. Once
a fault is asserted the sensor electrodes will no longer be scanned until the fault is cleared. In the event of multiple faults occurring
at the same time, the sensor controller will report the first fault that is detected during scanning.
6.4.1
Fault Register
The Fault Register is a read only register that shows the fault number under the current sensor conditions. Any write to the Fault
Register will clear the register, when in Stop mode. The Fault register cannot be cleared when the part is in a Run mode. The I2C
slave address of the Fault Register is 0x01.

MDF
More Data Flag – The More Data Flag shows whether or not data will remain in the
buffer after the current read.
0 No Data Remaining
1 Data Remaining
6
NDF
No Data Flag – The No Data Flag shows whether or not there is currently data in
the buffer.
0 Buffer currently has data
1 Buffer does not currently have data
5
OF
Overflow Flag – The Overflow Flag shows whether or not an overflow has occurred.
If this flag is high then the most current data was lost.
1 Overflow has occurred
4
TRF
Touch Release Flag – The Touch Release Flag shows if the current buffer entry is
a touch or release of a pad.
0 Pad is released
1 Pad is touched
3:0
BP
Buffered Position – The Buffered Position represents the electrode number that is
currently being displayed by the buffer.
0000 Encoding 0 – Buffered touch of electrode 1
