NOTE: x = Logic low
Initially (after reset), the TAS3002 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 terminal is activated, the TAS3002 device echoes its function over I2C to a TAS3001 device mapped
to address 6Ah. 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.
