Real Time Clock
The Real Time Clock (RTC) module of the XC161 is directly clocked via a separate clock
driver either with the on-chip auxiliary oscillator frequency (
f
RTC = fOSCa) or with the
prescaled on-chip main oscillator frequency (
f
RTC = fOSCm/32). It is therefore independent
from the selected clock generation mode of the XC161.
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:
– a reloadable 10-bit timer
– a reloadable 6-bit timer
– a reloadable 10-bit timer
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
maintain the correct system time even when intermediate resets are executed.
