Susan Yang：您可以看一下数据手册 www.ti.com.cn/…/tms320f28377s.pdf 的Table 4-3
Table 4-3 shows the GPIO muxed pins. The default for each pin is the GPIO function, secondary functions can be selected by setting both the GPyGMUXn.GPIOz and GPyMUXn.GPIOz register bits. The GPyGMUXn register should be configured prior to the GPyMUXn to avoid transient pulses on GPIO's from alternate mux selections.
