- Detailed Description - System Functions
The RTC module includes an alarm function. When the content of the RTC 1…4 registers equals the content of the
RTC Alarm 1…4 registers bit RTCAlarm will be set in the Interrupt 1 register. Furthermore the RTC module can
generate an interrupt every second (RTC1Sec will be set) and every minute (RTC1min will be set every time the 6-bit
second counter is reset to 0). For further details on interrupt generation please refer to Interrupt Controller on page
To avoid ambiguous behavior during write access to the RTC Alarm 1…4 registers any write access to the RTC Alarm
1 register will disable the alarm function; any subsequent write access to the RTC Alarm 4 will enable the alarm
function again.
