CONTROL REGISTER (REGISTER ADDRESS 0x80,
REGISTER ADDRESS 0x81)
The AD5933 has a 16-bit control register (Register Address 0x80
and Register Address 0x81) that sets the AD5933 control
modes. The default value of the control register upon reset is
as follows: D15 to D0 reset to 0xA000 upon power-up.
The four MSBs of the control register are decoded to provide
control functions, such as performing a frequency sweep,
powering down the part, and controlling various other
functions defined in the control register map.
The user may choose to write only to Register Address 0x80 and
not to alter the contents of Register Address 0x81. Note that the
control register should not be written to as part of a block write
command. The control register also allows the user to program
the excitation voltage and set the system clock. A reset command
to the control register does not reset any programmed values
associated with the sweep (that is, start frequency, number of
increments, frequency increment). After a reset command, an
initialize with start frequency command must be issued to the
control register to restart the frequency sweep sequence (see
Figure 34).
