Contains the lower two BCD digits of the year. Lower nibble (four bits) contains the value for years; upper nibble (four
bits) contains the value for 10s of years. Each nibble operates from 0 to 9. The range for the register is 0–99.
Contains the BCD digits of the month. Lower nibble (four bits) contains the lower digit and operates from 0 to 9; upper
nibble (one bit) contains the upper digit and operates from 0 to 1. The range for the register is 1–12.
Contains the BCD digits for the date of the month. Lower nibble (four bits) contains the lower digit and operates from 0
to 9; upper nibble (two bits) contains the 10s digit and operates from 0 to 3. The range for the register is 1–31. Leap
years are automatically adjusted for.
Lower nibble (three bits) contains a value that correlates to day of the week. Day of the week is a ring counter that counts
from 1 to 7 then returns to 1. The user must assign meaning to the day value, because the day is not integrated with the
date.
Contains the BCD value of hours in 24 hour format. Lower nibble (four bits) contains the lower digit and operates from
0 to 9; upper nibble (two bits) contains the upper digit and operates from 0 to 2. The range for the register is 0–23.
Contains the BCD value of minutes. Lower nibble (four bits) contains the lower digit and operates from 0 to 9; upper
nibble (three bits) contains the upper minutes digit and operates from 0 to 5. The range for the register is 0–59.
Contains the BCD value of seconds. Lower nibble (four bits) contains the lower digit and operates from 0 to 9; upper
nibble (three bits) contains the upper digit and operates from 0 to 5. The range for the register is 0–59.
