Notes
4. TCPWM stands for timer, counter, and PWM. If supported, the pad can be configured to any of these peripheral functions.
5. TCPWM connections on ports 0, 1, 2, and 3 can be routed through the Digital Signal Interconnect (DSI) to any of the TCPWM blocks and can be either positive
or negative polarity. TCPWM connections on port 5 are direct and can only be used with the specified TCPWM block and polarity specified above.
6. The main board needs to connect both GND connections (Pad 1 and Pad 32) on the module to the common ground of the system.
