5.9. Register Read/Write
The software's graphical user interface and property windows provide an easy, intuitive method of configuring the
device. In development, however, it is often useful to have low-level bytewise read/write interface to the tuner. The
GUI provides this interface under Window  Register Map.
Figure 26. “Register Map Window” shows an example read/write operation. The FM_RSQ_STATUS request is sent
with an ARGument of 0x00. The reply returned in the RESPonse fields.
Refer to the Programming Guide for detailed information on the register definitions and their arguments and
responses.
