S32K312 UART DSR Configuration

[KarthikRaja]

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.
