Configuration Register
The Configuration Register allows a user to reset the part, adjust Interrupt settings, and change the mode. The I2C slave address
of the Configuration Register is 0x0A.

Attention Pin
The Attention (ATTN) pin allows a user to externally set the Configuration Register’s DCE bit high. This is latched on a high to
low transition. Since the current mode of the device is enabled through the DCE this will cause duty cycling to be disabled and
change the current mode from Run2 to Run1, or Stop2 to Stop1 (depending on the previous state).
When in Run2 or Stop2 modes this is the only way to enable the I2C communication.

IRQR
Interrupt Rate – The Interrupt Rate Field selects the amount to multiply the MTP by
to determine the minimum delay between sequential Interrupts.
000 Encoding 0 – Sets the IRQR multiplication factor to 1
~
111 Encoding 7 – Sets the IRQR multiplication factor to 8

RST
Reset – Asserts a global reset of the sensor controller.
0 Reset Asserted
1 Reset Not Asserted
2
DCE
Duty Cycle Enable – The Duty Cycle Enable bit enables or disables duty cycling on
the MPR083. This bit is active low.
0 Duty Cycle Enabled (2 modes)
1 Duty Cycle Disabled (1 modes)
1
IRQEN
Interrupt Enable – The Interrupt Enable bit enables or disables the IRQ
Functionality.
0 IRQ Disabled
1 IRQ Enabled
0
RUNE
Run Mode Enable – The Run Mode Enable bit enables or disables scanning of the
electrodes for touch detection. This bit is active high.
0 Electrode Scanning Disabled (Stop modes)
1 Electrode Scanning Enabled (Run modes)
