Built-in 7-channel DMA controller (2 to 6 channels are available for a user.)



Clock and Timer



RTC



RTC function with the accuracy of sleep clock frequency



Clock and Calendar function: YY/MM/DD hh:mm:ss (24-hour clock) and day of the week



Alarm function: Alarm setting by hh:mm and either a date or a day, and an interrupt by the alarm generation



Leap year function (the exceptional procedure for every 100 years is not supported.)



RTC is working even in the Sleep and Backup modes.



Timer



BCTimer



3-channel hardware timer (One channel is dedicated to the system.)
