6.1.5
Memory Mapped Registers for DAP Data Memory
The following memory mapped registers are used for communication with the digital audio processor.
Table 6-1. Memory Mapped Registers
Address
Register
Comment
0x0300
Dither Seed
Sets the dither seed value
0x0301
PC Start
Sets the starting address of the
DAP
0x0302
Reserved
Note that TAS3204 has the same memory mapped registers distinction of upper and lower memory for
these registers.
6.2
Boot Up Sequence
On power up of the TAS3204 or immediatly following a reset, the slave interface is disabled and the
master interface is enabled. Using the master interface, the TAS3204 automatically tests to see if an I2C
EEPROM is at address 1010x. The value x can be chip select, other information, or don’t cares,
depending on the EEPROM selected. If an EEPROM is present and it contains the correct header
information and one or more blocks of program/memory data, the TAS3204 loads the program, coefficient,
and/or data memories from the EEPROM. If a EEPROM is present, the download is complete when a
header is read that has a zero-length data segment. At this point, the TAS3204 disables the master I2C
interface, enables the slave I2C interface, and starts normal operation.
If no EEPROM is present or if an error occurred during the EEPROM read, TAS3204 disables the master
I2C interface, enables the slave I2C interface, and loads the default configuration stored in the ROM. In
this default configuration, the TAS3204 streams audio from input to output if the GPIO pin is LOW.
The master and slave interfaces do not operate simultaneously.
