The Pins tool included in the MCUXPresso Config Tools can help you configure routing of individual pins. It's also capable of configuring modulation features of certain peripherals. Prerequisites MCUXpresso Config Tools OR MCUXpresso IDE NXP Kinetis processor with LPTMR, UART, or FTM peripherals supporting signal modulation Toolchain project using the MCUXpresso Pins tool Workflow If you want to configure signal modulation for LPTMR, UART, and FTM peripherals, you can do so by using the SIM option. In the Pins tool, select the Peripheral Signals view. From the list of peripheral signals, select SIM by clicking the box. In the Peripheral SIM window, choose the signal you want to route and the modulation signal. Signals available for modulations include the MOD string. In the Routable pins / signal routes, choose the pin / signal route. Update code by clicking Update code and build with your IDE/toolchain.
