Can someone please help to provide information or sample code for 9bit data communication on UART.

I want to read 9 Bit data in My controller coming from another device.

I t will be very helpful if someone share a working code for 9 bit data read write with interrupt ISR.

Hello Pradeep,

We do not have such a code example available unfortunately, but TivaWare does include 9-bit UART API's you can use.

You can reference the DriverLib User Guide for 9-bit UART mode, starting on Page 557 which outlines the 4 API's available for 9-bit operation: http://www.ti.com/lit/ug/spmu298d/spmu298d.pdf
