Preliminary
3.9
The Real Time Clock (RTC) module of the XC2766X can be clocked with a clock signal
selected from internal sources or external sources (pins).
The RTC basically consists of a chain of divider blocks:
•
•
•
All timers count up. Each timer can generate an interrupt request. All requests are
combined to a common node request.
Figure 9
Note: The registers associated with the RTC are only affected by a power reset.
