TMDX570LC43HDK: TMDX570LC43HDK Button Control

Hi,

I solved my issue.

My solution is below and led blink with push button.

I don't understand why the 6th bit of the din register is 2.

code:

/** @file HL_sys_main.c
* @brief Application main file
* @date 11-Dec-2018
* @version 04.07.01
*
* This file contains an empty main function,
* which can be used for the application.
