Real Time Clock
The Real Time Clock (RTC) module of the C161S 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 (
f
RTC = fOSC/32) and is
therefore independent from the selected clock generation mode of the C161S. 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

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.
