2.6 Pin Configuration and PinMux

Figure 2-6 shows what parameters are included in Pin Configuration and PinMux block.

Pin Configuration and PinMux Figure 2-12 Pin Configuration and PinMux
  • Pin Configuration
    • TX Pin and RX Pin: configures digital IOMUX features on a dedicated pin. Such as internal pull-up or pull-down resistor, invert output, drive strength and high impedance settings. TI recommends to keep default configuration on the IOMUC configurations for CAN applications.
  • Pin Mux
    • MCAN Peripheral: some MSPM0 devices are integrated with multiple MCAN modules. Users can choose which MCAN module is configured here.
    • TX/RX Pin: configures the GPIO pins for MCAN TX and RX function.
