quency calculations in the FFT window. This
will also help the software decide which func-
tions can be performed reliably with the evalu-
ation system.
Output function should be set to the default Ac-
tive Low, and the Eout / Edir Function should
be set to the default Normal. This applies only
to the CDB5461 evaluation system, and not to
the CS5461 chip itself.
2.4.3 Configuration Register
2.4.4 Mask Register / Status Register
In the Configuration Register box, the contents
of the Configuration Register can be modified
by typing a hexadecimal value in the HEX:
box, or by changing any of the values below
the HEX: box to the desired settings. Although
the CDB5461 software allows the user to mod-
ify any of the bits in the Configuration Register,
changing certain bits may cause the software
and board to behave erratically. For the evalu-
ation system to function properly, the Interrupt
The Mask and Status Registers are displayed
in hexadecimal and decoded in this box to in-
dicate each bit’s function. The Mask Register
can be modified by typing a value in the HEX:
box, or by checking the appropriate check box-
es for the bits that are to be masked. The Sta-
tus Register cannot be directly modified. It can
only be reset by pressing the Clear Status
Register Button. The HEX: box for this regis-
