6410的otg寄存器如何操作？
怎么关闭6410的otg功能，如何写寄存器？
static void InitializeOTGCLK(void)
{
volatile S3C6410_SYSCON_REG *pSysConReg = (S3C6410_SYSCON_REG *)OALPAtoVA(S3C6410_BASE_REG_PA_SYSCON, FALSE);
volatile OTG_PHY_REG *pOtgPhyReg = (OTG_PHY_REG *)OALPAtoVA(S3C6410_BASE_REG_PA_USBOTG_PHY, FALSE);

pSysConReg->HCLK_GATE |= (1<<20);

pSysConReg->OTHERS |= (1<<16);

pOtgPhyReg->OPHYPWR = 0x0; // OTG block, & Analog bock in PHY2.0 power up, normal operation

//pOtgPhyReg->OPHYCLK = 0x20; // Externel clock/oscillator, 48MHz reference clock for PLL
pOtgPhyReg->OPHYCLK = 0x0; // External crystal, 48MHz reference clock for PLL

pOtgPhyReg->ORSTCON = 0x1;
Delay(100);
pOtgPhyReg->ORSTCON = 0x0;
Delay(100); //10000

pSysConReg->HCLK_GATE &= ~(1<<20);

}

上面是初始化，那怎么关闭呢？

[解决办法]
pSysConReg->HCLK_GATE &= ~(1<<20); 这个不是关闭了吗
