RTCPTR1:RTCPTR0: RTCC Value Register Window Pointer bits
Points to the corresponding RTCC Value registers when reading RTCVALH and RTCVALL registers; the
RTCPTR<1:0> value decrements on every read or write of RTCVALH until it reaches ‘00’.
RTCVAL<15:8>:
00 = MINUTES
01 = WEEKDAY
10 = MONTH
11 = Reserved
RTCVAL<7:0>:
00 = SECONDS
01 = HOURS
10 = DAY
11 = YEAR
CAL7:CAL0: RTC Drift Calibration bits
01111111 = Maximum positive adjustment; adds 508 RTC clock pulses every one minute
...
01111111 = Minimum positive adjustment; adds 4 RTC clock pulses every one minute
00000000 = No adjustment
11111111 = Minimum negative adjustment; subtracts 4 RTC clock pulses every one minute
...
10000000 = Maximum negative adjustment; subtracts 512 RTC clock pulses every one minute
Legend:
R = Readable bit
-n = Value at POR
Note 1: The RCFGCAL register is only affected by a POR.
