The RTCCFG 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.
The RTCWREN bit can only be written with the unlock sequence (see Example 17-1).
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 ALRMRPT registers can change while reading if a rollover ripple results
0 = RTCVALH, RTCVALL and 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 clock output is enabled
0 = RTCC clock output is 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<15:8> until it reaches ‘00’.
RTCVALH:
00 = Minutes
01 = Weekday
10 = Month
11 = Reserved
RTCVALL:
00 = Seconds
01 = Hours
10 = Day
11 = Year
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.
