when in calendar mode with RTCC_CCx_CTRL_COMPBASE = CNT. The SECU, SECT, MINU, MINT, HOURU, HOURT, MONTHU,
and MONTHT bitfields in RTCC_CCx_TIME and RTCC_CCx_DATE are compared to the corresponding bitfields in RTCC_DATE and
RTCC_TIME. The DAYU and DAYT bitfields in RTCC_CCx_DATE will be compared to {RTCC_DATE_DAYOMT, RTCC_DATE_DAYO-
MU} if DAYCC in RTCC_CCx_CTRL is set to MONTH. If DAYCC in RTCC_CCx_CTRL is set to WEEK, the DAYU and DAYT bitfields in
RTCC_CCx_DATE will be compared to {0b000, RTCC_DATE_DAYOW}.
