DRV8320: DRV832x SPI question

Part Number: DRV8320

Hi team 

Good day

Customer have 2 questions want to query.

1. During the first frame of the read operation, it seems like we still need to have 16 SCLK cycles, so after sending WO =1 and the 4 bit address, does it matter what's the value of the remaining 11 bits of data?

2. Assuming we are not concerned about new values being written into a particular address, can we utilize the write operation to read out the content of the register within a single frame?
because the datasheet mentioned that: For a write command, the existing data in the register being written to is shifted out on the SDO pin following the 5-bit command data.

Best regards
