The Real Time Clock (RTC) module of the XC164GM is directly clocked via a separate
clock driver with the prescaled on-chip main oscillator frequency (
therefore independent from the selected clock generation mode of the XC164GM.
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.
