14.4.3 RTC Modulo Register: High (RTC_MODH)

RTC_MODH, together with RTC_MODL, indicates the value of the 16-bit modulo
value.

Field
MODH RTC Modulo High
These sixteen read/write bits, MODH and MODL, contain the modulo value used to reset the count to
0x0000 upon a compare match and set the RTIF status bit. A value of 0x00 of the MODH an MODL sets
the RTIF bit on each rising edge of the prescaler output. Reset sets the modulo to 0x00.

14.4.4 RTC Modulo Register: Low (RTC_MODL)

RTC_MODL, together with RTC_MODH, indicates the value of the 16-bit modulo
value.
Address: 306Ah base + 3h offset = 306Dh
