A Default Register Configuration
TheregistersintheHFA3860areaddressedwith6-bitnumbers
where the lower 2 bits of an 8-bit hexadecimal address are left
as unused. This results in the addresses being in increments of
4 as shown in the table below. Table 11 shows the register
values for a default 802.11 configuration with various rate
configurations. The data is transmitted as either DBPSK,
DQPSK, BMBOK, or QMBOK 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.
