DRV2665 Override Bit

Hello, I am trying to control a DRV2665 using an Arduino Due board. I have implemented the application circuit listed in the datasheet on page 20 with the suggested components (chip is mounted to a small prototype PCB and inserted into a breadboard - all other components are on the breadboard). The chip is powered with 3.3V and the inputs are being held at 3.3V on the IN+ and Gnd on the IN-. A piezo actuator with a 50nF load capacitance is attached.  I am able to talk to the DRV2665 via I2C. If I clear the standby bit, enable the Analog inputs and gain settings and then try to toggle the override bit in register 0x02, the chip seems to reset (if I immediately read the registers after setting the override bit I get back 0x28 from register 0x01 and 0x40 from register 0x02. No output appears between Out+ and Out-. Writes to the FIFO in digital mode also do not generate an output. I have several of these board mounted chips which all produce the same effect. Any suggestions where my error is? The layout guidelines do imply the external components should be very close to the chip pins which they relatively are not using my breadboard setup - still I would expect some output.
