The RTCCSEC register is enabled when bits RTCCMP1 to RTCCMP0 in the RTCCR2 register are 01b,
10b, or 11b (any compare mode).
SCMP03-SCMP00 (1st Digit of Second Compare Data Bit) (b3-b0)
SCMP12-SCMP10 (2nd Digit of Second Compare Data Bit) (b6-b4)
Set a value between 00 and 59 by the BCD codes.
Write to these bits when the BSY bit in the RTCSEC register is 0 (not while data is updated).
