DSP Instruction Set
SLES235 – JULY 2008 ....................................................................................................................................................................................................... www.ti.com
The superset instruction word maintains backward compatibility with the 54-bit instruction word of the TAS3218
device, since the 54 bit instruction word required dummy storage of 2 bits in the EEPROM.
Figure 31. Instruction Word
As shown in Figure 32 the extension bit designates an offset of 1K to all three addresses in the instruction word.
However, it should be noted that both data and coefficient memory addresses above the 1K boundary are
reserved for housekeeping processing tasks. Any attempt to write to these addresses may corrupt the audio
output.
