新手，遇到程序有点不懂，望指教一下

typedef struct
{
volatile struct EPWM_REGS *EPwmRegHandle;
Uint16 EPwm_CMPA_Direction;
Uint16 EPwm_CMPB_Direction;
Uint16 EPwmTimerIntCount;
Uint16 EPwmMaxCMPA;
Uint16 EPwmMinCMPA;
Uint16 EPwmMaxCMPB;
Uint16 EPwmMinCMPB;
}EPWM_INFO;

EPWM_INFO epwm1_info;
EPWM_INFO epwm2_info;
EPWM_INFO epwm3_info;

问题1:上面volatile struct EPWM_REGS *EPwmRegHandle;这里*代表什么意思

问题2：EPWM_INFO代表什么意思

问题3：EPWM_INFO epwm1_info;又代表什么意思

user6228385：没人帮忙？
