你好，关于CYPD3125-40LQXI，首先，我将CG3作为DFP工作，并在cc1和cc2上激活RP。当UFP通过EMCA连接时，我认为CG3必须通过控制VBuSupPcTrL0/ 1引脚来打开VBUS FET。Q1）如何知道cc1或cc2是连接的，在ccg FW中连接到UFP的电压是否正确？有什么中断发生吗？Q2）我应该如何控制vBuSupPcTrL0/ 1？准备了什么API？最好的问候， 以上来自于百度翻译 以下为原文Hello, About CYPD3125-40LQXI, I work CCG3 as DFP at first and I will activate Rp on CC1 and CC2.And when UFP is connected though EMCA, I think that CCG3 have to open VBUS FET by controlling VBUS_P_CTRL0/1 pins. Q1) How can I know CC1 or CC2 is connected and the voltage is correct for connecting to UFP in CCG FW? any interrupt happen? Q2) How should I control the VBUS_P_CTRL0/1? any API prepared?
