11.2 MAIN CLOCK CONTROLLER WITH REAL TIME CLOCK (MCC/RTC)
The Main Clock Controller consists of a real time
clock timer with interrupt capability
11.2.1 Real Time Clock Timer (RTC)
The counter of the real time clock timer allows an
interrupt to be generated based on an accurate
real time clock. Four different time bases depend-
ing directly on f
functionality is controlled by four bits of the MCC-
SR register: TB[1:0], OIE and OIF.
