I am currently using colibri imx 7 som. I am trying to initialize the quadrature encoder mode with ouput compare match. The code given below the intialization of registers as per the instructions given in the manual. I do see change in the FTM count register even though the enoder is not moving. Are there any other changes I need to make to the FTM registers or any other registers in conjuntion to make the code functional
