Parameters
Return Codes None.
Purpose
Synopsis
The RTC can be enabled and disabled via the PowerON() and PowerOFF() or RTCClk_Control ()
functions. The new values will not be loaded until the RTCLoad bit (bit 5) of the RTCCtl register
is set (HI).
RTCCnt: Input parameter
32-bit RTC counter value.
RTCAcc[3]: Input parameter
24-bit accumulator value. Normally these values are to be initialized only once
during the manufacturing phase.
RTCTrim[3]: Input parameter
24-bit signed trimmer value. This is the offset value used to correct the quartz crystal
drift. It is the number of ticks between each correction of the Real Time Clock. Use
a negative numbers to decrease the tic-count by one and a positive number to
increase the tick-count by 1.
Extract the current Real Time Clock control, counter, accumulator, and trimmer values.

}
RTCCtl: Output parameter
Current Real Time Clock Control register value (setting).
RTCCnt: Output parameter
Current Real Time Clock Counter value.
RTCAcc[3]: Output parameter
Current Real Time Clock accumulator value.
RTCTrim[3]: Output parameter
Current Real Time Clock Trimmer value.
Extract current calendar Time. Time conversion is done by the Gregorian/Julian conversion
method as defined on website: http://webexhibits.org/calendars/calendar-christian.html.
