A Default Register Configuration
TheregistersintheHFA3861areaddressedwith7-bitnumbers
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.
