Connect the MC-57xx and the TAS5708(TAS5710)EVM boards by locating pin 1 on each board, indicated
by a small white triangle. The MC-57xx plugs down onto the TAS5708(TAS5710)EVM board (i.e., the
TAS5708(TAS5710)EVM board fits underneath the MC57xxPSIA board). Pin 1 on each board must be
connected to each other.

Install the EVM software on the personal computer (PC) before powering up the board. After connecting
the loudspeakers or other loads, power supplies, and the data line, power up the 5-V power supply first;
then power up the PVCC power supply. It is recommended initially to set the PVCC level to 10 V, then
ramp it up to 20 V to verify cable connections.
