RTC Count— These eight read-only bits contain the current value of the 8-bit counter. Writes have no effect to this
register. Reset, writing to RTCMOD, or writing different values to RTCLKS and RTCPS clear the count to 0x00.
RTC Modulo — These eight read/write bits contain the modulo value used to reset the count to 0x00 upon a
compare match and set the RTIF status bit. A value of 0x00 sets the RTIF bit on each rising edge of the prescaler
output. Writing to RTCMOD resets the prescaler and the RTCCNT counters to 0x00. Reset sets the modulo to
0x00.
