Real Time Clock
The Real Time Clock (RTC) module of the C161CS/JC/JI 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 via a
separate clock driver with the on-chip main oscillator frequency divided by 32
(
therefore independent from the selected clock generation mode of the C161CS/JC/JI.
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
