I am starting my first project with the STUW813000. I don't seem to find a clear answer to the following 2 questions:My power consumption is on the level of 6-7mA on the supply line of 5.5V. No ref signal yet present, HW_PD@GND, PD_RF1@GND, PD_RF2@3.3V. Is this normal under these conditions?(if not caused by 1) I am absolutely unable to establish SPI communication with the device. For a test I intended to read the status register 0x0A, for which I am sending byte (0b1101000: 0x), taking into account the first bit should be 1 for reading. No data received. I tried to send a sequence of 4 bytes (filled with zeros) to make up the 32-bit pattern but no success. The SPI lines are operated correctly, matching the pattern from the manual. No activity on the MISO line from the STUW.Thanks for any hints.

First steps with STUW813000
