怎么防止GPIO口一上电就就是高电平



怎么防止GPIO口一上电就就是高电平?

GPIO也有2k的下拉电阻不管用,将下拉电阻地质200欧姆才可以,用的28069,在28035上没有此问题,难道就是因为28069运行速度快?

主程序:

void main(void)
{

InitSysCtrl();//感觉从程序一上电后,GPIO就是高电平
InitGpio();//直到在初始GPIO中,将GPIO拉低,高电平才消失
InitEPwm();
memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize);

InitFlash();


DINT;
