Hi Pavlin,
It appears like the device has either been damaged or there is some type of connection problem to the board. If you have a second board, please try it for confirmation.
The R1 and R3 values appear to be incorrect. It is possible this could have damaged the device. 1mA through R1/R3 violates the absolute maximum voltage on the xISENP pins. Typically, R1 and R3 are less than 1 Ohm. Please address this prior to the next time the device is powered up.
What is the recommended motor current?
If you have a second board or replace the device, please check for solder bridges and pin to pin shorts prior to power up. Once powered up, raise SLEEPn and measure the VINT and V5 and VCP voltages. If good, then proceed to SPI writes to enable the outputs.
BIN1 and BIN2 can be left unconnected. There an internal pulldown resistors.
