* DESCRIPTION
* This function implements registration of external interrupts
*
* CALLS
*
* PARAMETERS
* eintno - External interrupt vector number(外部中断号)
* Dbounce_En - Debounce control enable(判断当前是否可用)
* ACT_Polarity - Interrupt polarity(设置高电平触发还是低电平触发)
* reg_hisr - Registered hisr(响应函数)
* auto_umask - A flag instruct the systerm to do unmask after
* invoking the registered HISR
