S32K312 UART DSR Configuration

Hi,

We are using S32K312 EVB board and trying to integrate with UBLOX Bluetooth module using UART. To put the UBLOX module in sleep mode it makes use of UART DSR pin(High/Low). How should we connect to S32K312 MCU and is there any UART circuit for UART communication.

Let us know the configuration to use UART DSR option.

Hi @KarthikRaja

I am afraid that S32K312 devices do not have an external connection for Data set ready (DSR_B), This is only internally connected to DTR_B for Loop mode. What I can recommend, if the signal is required, the following S32K3 derivatives, have been confirmed to have this signal: S32K310, S32K311, S32K322, S32K341, S32K342, and S32K3x8.
