According to the AD9273 datasheet, all registers except Register 0x00, 0x02, 0x04, 0x05, and 0xFF are buffered with a master-slave latch and require writing to the transfer bit. I would like to read the chip ID from the register 0x01. This is a read-only register, but from the datasheet, it means that this register is also buffered with a master-slave latch.
Does this mean that I need to write to the DEVICE_UPDATE register at 0xFF first in order to read from the chip ID register at 0x01? Right now, I did not write to this DEVICE_UPDATE register. I am sure that I am sending the correct bits to read the chip ID, but I am not getting the correct results as expected and I am wondering if that is because I did not write to the DEVICE_UPDATE register first?
