Part Number: TPS65982

Dear TI Sir :

TPS65982 pin L4 LSX_R2P DESCRIPTION : Ground pin with between 1-kΩ and 5-MΩ resistance when unused.

But I found TPS65982 pin L4 (LSX_R2P) floating from TPS65982 EVM User's Guide.

Which one is right ? Thanks.

Hi Terry,

The suggestion from the datasheet is correct, please ground with between 1-kΩ and 5-MΩ resistance when unused.

Okay, also the following pins UART_TX(E2),UART_RX(F2),LSX_R2P(L4),DEBUG1(L2),DEBUG2(K2). The datasheet is different from TPS65982 EVM User's Guide.
Do I still follow the datasheet?Unused pins GPIOs and SPI）also connected to the ground?
