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 (

fRTC = fOSC/32)

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

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.
