3.4 Main Controller Circuit

The peripheral circuit of the MSPM0C1104 mainly consists of the reset circuit and the program burning interfaces, as shown in Figure 3-5.

In this solution, the assignment of pin functions for MSPM0C1104 can refer to Table 3-1. TIM0_CC0 and TIM0_CCC0 are complementary PWM signals, and TIM0_CC1 and TIM0_CCC1 are complementary PWM signals. Reserving the UART interface is for convenient debugging and only four signals are required for burning, including SWCLK, SWDIO, RST and GND.
