The ck_wut period is selected through WUCKSEL[2:0] bits of the RTC_CR register. When WUCKSEL[2] = 1, the wakeup timer becomes 17-bits and WUCKSEL[1] effectively becomes WUT[16] the most-significant bit to be reloaded into the timer. The first assertion of WUTF occurs between WUT and (WUT + 1) ck_wut cycles after WUTE is set. Setting WUT[15:0] to 0x0000 with WUCKSEL[2:0] = 011 (RTCCLK/2) is forbidden.

0x40002828 B REGISTER CALR: RTC calibration register
0x40002828 C FIELD 00w09 CALM (rw): Calibration minus The frequency of the calendar is reduced by masking CALM out of 220 RTCCLK pulses (32 seconds if the input frequency is 32768Hz). This decreases the frequency of the calendar with a resolution of 0.9537ppm. To increase the frequency of the calendar, this feature should be used in conjunction with CALP. See .
0x40002828 C FIELD 13w01 CALW16 (rw): Use a 16-second calibration cycle period When CALW16 is set to 1, the 16-second calibration cycle period is selected. This bit must not be set to 1 if CALW8 = 1. Note: CALM[0] is stuck at 0 when CALW16 = 1. Refer to calibration.
0x40002828 C FIELD 14w01 CALW8 (rw): Use an 8-second calibration cycle period When CALW8 is set to 1, the 8-second calibration cycle period is selected. Note: CALM[1:0] are stuck at 00 when CALW8 = 1. Refer to digital calibration.
0x40002828 C FIELD 15w01 CALP (rw): Increase frequency of RTC by 488.5ppm This feature is intended to be used in conjunction with CALM, which lowers the frequency of the calendar with a fine resolution. if the input frequency is 32768Hz, the number of RTCCLK pulses added during a 32-second window is calculated as follows: (512 * CALP) - CALM. Refer to .
0x4000282C B REGISTER SHIFTR: RTC shift control register
0x4000282C C FIELD 00w15 SUBFS (wo): Subtract a fraction of a second These bits are write only and is always read as zero. Writing to this bit has no effect when a shift operation is pending (when SHPF = 1, in RTC_ICSR). The value which is written to SUBFS is added to the synchronous prescaler counter. Since this counter counts down, this operation effectively subtracts from (delays) the clock by: Delay (seconds) = SUBFS / (PREDIV_S + 1) A fraction of a second can effectively be added to the clock (advancing the clock) when the ADD1S function is used in conjunction with SUBFS, effectively advancing the clock by: Advance (seconds) = (1 - (SUBFS / (PREDIV_S + 1))). Note: Writing to SUBFS causes RSF to be cleared. Software can then wait until RSF = 1 to be sure that the shadow registers have been updated with the shifted time.
0x4000282C C FIELD 31w01 ADD1S (wo): Add one second This bit is write only and is always read as zero. Writing to this bit has no effect when a shift operation is pending (when SHPF = 1, in RTC_ICSR). This function is intended to be used with SUBFS (see description below) in order to effectively add a fraction of a second to the clock in an atomic operation.
