A Default Register Configuration
The registers in the HFA3861B are addressed with 7-bit
numbers where the lower 1 bit of an 8-bit hexadecimal address
is left as unused. This results in the addresses being in
increments of 2 as shown in the table below. Table 9 shows the
register values for a default 802.11 configuration with various
rate configurations. The data is transmitted as either DBPSK,
DQPSK, or CCK depending on the configuration chosen. It is
recommended that you start with the simplest configuration
(DBPSK) for initial test and verification of the device and/or the
radio design. The user can later modify the CR contents to
reflect the system and the required performance of each
specific application.
