Preliminary
3.9
The Real Time Clock (RTC) module of the XC226x can be clocked with a selectable
clock signal from internal sources (oscillators or PLL) 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.

Note: The registers associated with the RTC are only affected by a power reset.
