修改复位电压

Other Parts Discussed in Thread: LM3S811

由于做短路保护,所以M4掉电比较快,

不知道这条语句怎么用
SysCtlBrownOutConfigSet(unsigned long ulConfig, unsigned long ulDelay)
{
    ASSERT(!(ulConfig & ~(SYSCTL_BOR_RESET | SYSCTL_BOR_RESAMPLE)));
    ASSERT(ulDelay < 8192);

    HWREG(SYSCTL_PBORCTL) = (ulDelay << SYSCTL_PBORCTL_BORTIM_S) | ulConfig;
}

PBORCTL 寄存器不是只有第一位和第二位起作用吗?
