The RCFGCAL register is only affected by a POR.
A write to the RTCEN bit is only allowed when RTCWREN = 1.
This bit is read-only; it is cleared to ‘0’ on a write to the lower half of the MINSEC register.
RTCC CONTROL REGISTERS
RTCEN: RTCC Enable bit
1 = RTCC module is enabled
0 = RTCC module is disabled
Unimplemented: Read as ‘0’
RTCWREN: RTCC Value Registers Write Enable bit
1 = RTCVALH and RTCVALL registers can be written to by the user
0 = RTCVALH and RTCVALL registers are locked out from being written to by the user
RTCSYNC: RTCC Value Registers Read Synchronization bit
1 = RTCVALH, RTCVALL and ALCFGRPT registers can change while reading due to a rollover ripple
0 = RTCVALH, RTCVALL or ALCFGRPT registers can be read without concern over a rollover ripple
HALFSEC: Half-Second Status bit
1 = Second half period of a second
0 = First half period of a second
RTCOE: RTCC Output Enable bit
1 = RTCC output enabled
0 = RTCC output disabled
RTCPTR<1:0>: RTCC Value Register Window Pointer bits
Points to the corresponding RTCC Value registers when reading the 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

resulting in an invalid data read. If the register is read twice and results in the same data, the data
can be assumed to be valid.
