The Real Time Clock (RTC) module of the XC164 is directly clocked via a separate clock
driver with the prescaled on-chip oscillator frequency (
independent from the selected clock generation mode of the XC164.
The RTC basically consists of a chain of divider blocks:
• a selectable 8:1 divider (on - off)
• the reloadable 16-bit timer T14
• the 32-bit RTC timer block (accessible via registers RTCH and RTCL), made of:
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 not affected by a reset in order to
