CONTROL REGISTER DETAILS
ADDRESS 2048 TO ADDRESS 2055 (0x0800 TO
0x0807)—INTERFACE REGISTERS
The interface registers are used in self-boot mode to save
parameters that need to be written to the external EEPROM.
The ADAU1702 then recalls these parameters from the
EEPROM after the next reset or power-up. Therefore, system
parameters such as volume and EQ settings can be saved during
power-down and recalled the next time the system is turned on.
There are eight 32-bit interface registers, which allow eight 28-bit
(plus zero padding) parameters to be saved. The parameters to
be saved in these registers are selected in the graphical
programming tools. These registers are updated with their
corresponding parameter RAM data once per sample period.
An edge, which can be set to be either rising or falling, triggers
the ADAU1702 to write the current contents of the interface
registers to the EEPROM. See the Self-Boot section for details.
The user can write directly to the interface registers after the
interface registers control port write mode (IFCW) in the DSP core
control register has been set. In this mode, the data in the registers
is written from the control port, not from the DSP core.
