Operation
3.1.5 EEPROM A1 Select
The TSC2301EVM loads its firmware from an onboard EEPROM. In order to
use the firmware in this EEPROM, its A1 address line must be pulled low, so
JMP6 should stay installed for normal use.
This jumper may be removed when firmware updates are to be made.
3.2 I/O Connector and Signals
The various connectors on the TSC2301EVM are described in this section.
3.2.1 GPIO Connector
This 12-pin header provides access to the six GPIO pins on the TSC2301.

3.2.2 Mono Out Connector
The TSC2301 has a monaural output, which can be driven either from the
analog bypass input or a mono mix of the stereo outputs, selectable under
software control. This signal is routed to a mono power driver on the
TSC2301EVM, and an 8-Ω or greater speaker may be connected to this driver
through J2.

3.2.3 Audio Connectors
The TSC2301 audio inputs and outputs are routed through these stereo
(TIP/RING/SLEEVE) 3.5 mm jacks. Note the polarity of channel assignments
for these connectors.
