Real Time Clock
The Real Time Clock (RTC) module of the C167CS consists of a chain of 3 divider
blocks, a fixed 8:1 divider, the reloadable 16-bit timer T14, and the 32-bit RTC timer
(accessible via registers RTCH and RTCL). The RTC module is directly clocked with the
on-chip oscillator frequency divided by 32 via a separate clock driver (
and is therefore independent from the selected clock generation mode of the C167CS.
All timers count up.
The RTC module can be used for different purposes:
• System clock to determine the current time and date
• Cyclic time based interrupt
• 48-bit timer for long term measurements
Figure 8
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.
