Real Time Clock
The Real Time Clock (RTC) module of the C164CI consists of a chain of 3 divider blocks, a fixed 8-
bit 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 C164CI. 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
