I used one TPS92662 in my projection. MCU connected to TPS92662 by RX, TX. There is one spare group of RX/TX, how to deal with the spare channel?
Hello,
This is the response I received for the extra RX/TX pins:
"The RX and TX pins (along with SYNC and CLK pins) are physically connected internally. The pins are design to help layout a single sided PCBA. The unused RX, TX, SYNC, and CLK pins may be left open."
Regards,
