7.4
Test Mode
Terminal 9 (TEST) is tied low in normal operation. This function is reserved for factory test and must not be asserted.
7.5
Internal Interface
Figure 7–3 shows the block diagram of the interface between the microcontroller and its peripheral blocks.
7.6
GPI Terminal Programming
During initialization, the microcontroller fetches a control byte from its EPROM or receives a command from I2C.
7.6.1
Switch Interface
The six GPI terminals are programmed to operate in the following manner:

NOTE: x = Logic low
Initially (after reset), the TAS3004 GPI is set to control volume, bass, and treble. Simultaneously setting GPI bits 1
and 5 low for 1 second changes the function of the GPI terminals to control mute and equalization.
To return to volume, bass, and treble control, simultaneously set GPI terminals 2 and 3 low for 1 second.
When a GPI switch is activated, the TAS3004 device echoes its function over I2C to a TAS3001 device mapped to
address x6Ah. Therefore, a system with two audio equalization chips can be implemented without the need for a
microcontroller.
7.6.2
GPI Architecture
The GPI provides simple but flexible input port to activate the input parameters. Each terminal input is an active logic
low.
