RTC Control
The operating behavior of the RTC module is controlled by the RTCCON register. The
RTC starts counting by setting the RTCR run bit. After reset, the run bit is set and the
RTC automatically starts operation. Setting bits T14DEC or T14INC allows the T14 timer
to be manually and asynchronously decremented or incremented. These bits are cleared
by hardware after the decrement/increment operation. The RTC is only reset in case of
a hardware reset, so it keeps on running during idle and sleep mode.
Cyclic Interrupt Generation
The RTC module can generate an interrupt request RTC_INT whenever timer T14
overflows and is reloaded. This interrupt request may be used, for example, to provide
a system time tick, independent of the CPU clock frequency, without loading the general
purpose timers, or to wake up regularly from idle mode. The T14 overflow interrupt
(RTC_T14INT) cycle time can be adjusted via the timer T14 reload register T14REL. The
32 bit timer (RTCL and RTCH) can be divided into smaller reloadable timers. Each sub-
timer can be programmed for an overflow on different time bases (e.g. second, hour,
minute, day). With each timer overflow an RTC interrupt is generated. All these RTC
interrupts are ored within the RTC module via the interrupt subnode RTCISNC to one
interrupt request RTC_INT. This interrupt RTC_INT is one source of another interrupt
subnode ISNC in the interrupt controller. The other interrupt input of subnode ISNC is
disconnected in the M2. With typical values of T14REL = F448
