I'm trying to use the RTC_event of the PCD6001. I've put a "sbit RTC_interrupt_Enable 0xEF" and when i try to set the RTC_interrupt_Enable to '1', the compilator say me that the variable is undefined, but as u see, i've defined it with the sbit command. But it's work very well with the Global Interrupt Enable, i set a "sbit" to adress it, and i can set it to one without any errors. Whats the problems please ? Thanks!
