2.4.4
In the Configuration Register panel, the contents of the Configuration register can be modified by typing a hexadec-
imal value in the HEX: field, or by changing any of the values below the HEX: field to the desired settings. Although
the CDB5461AU software allows the user to modify any of the bits in the Configuration register, changing certain
bits may cause the software and board to behave erratically. For the evaluation system to function properly, the In-
terrupt Output field should be set to the default, Active Low setting, and E1, E2 Function field should be set to the
default Normal. This applies only to the CDB5461AU evaluation system, and not to the CS5461A chip itself.
2.4.5
The Mask and Status registers are displayed in hexadecimal and decoded in this box to indicate each bit's function.
The Mask register can be modified by typing a value in the HEX: field, or by checking the appropriate check boxes
for the bits that are to be masked. The Status register cannot be directly modified. It can only be reset by pressing
the Clear Status Register button. The HEX: field for this register, and the associated “lamps” are for display only. A
lamp that is on means that the corresponding bit in the Status Register is set (except the Invalid Command bit, which
is inverted). The value present in the Mask register may be changed by the software during certain operations to
provide correct functionality of the CDB5461AU board.
2.4.6
These fields display the values of the corresponding register in both hexadecimal and decimal format. Each register
can be modified by typing a value in the corresponding Value: or HEX: field.
2.4.7
The Control register contains various bits used to activate or terminate various features of the CS5461A. Refer to
the CS5461A data sheet for descriptions of these bits. The user is able to set or clear each bit individually. The value
of the Control register is displayed in the HEX: field. Most of the Control register bits are reserved or unused. Only
the usable bits are displayed in the Setup window.
