ADAU1701
Rev. B | Page 28 of 52
The writeback function writes data from the ADAU1701
interface registers to the second page of the self-boot EEPROM,
Address 32 to Address 63. Starting at EEPROM Address 26
(so that the interface register data begins at Address 32), the
EEPROM should be programmed with six bytes—the message
byte (0x01), two length bytes, the chip address (0x00), and the
2-byte subaddress for the interface registers (0x08 0x00). There
must be a message to the DSP core control register to enable
writing to the interface registers prior to the interface register
data in the EEPROM. This should be stored in EEPROM
Address 0. No-op messages (0x03) can be used in between
messages to ensure that these conditions are met.
The ADAU1701 writes to EEPROM Chip Address 0xA0. The
LSBs of the addresses of some EEPROMs are pin configurable; in
most cases, these pins should be tied low to set the address to 0xA0.
The maximum number of bytes that is written back from the
ADAU1701 is 35 (eight 4-byte interface registers plus three
bytes of EEPROM-addressing overhead). With SCL running at
384 kHz, the writeback operation takes approximately 73 μs to
complete after being triggered. Ensure that sufficient power is
available to the system to allow enough time for a writeback to
complete, especially if the WB signal is triggered from a falling
power supply voltage.
