This read/write register contains the current value of the month counter.
This register can be read at any time without affecting the counter count.
Writing to this register loads the value to the month counter and the
counter continues to count from this new value.
The month counter rolls over to 1 ($01) after reaching 12 ($0B). Writing
a value other than 1 to 12 to this register has no effect.
This read/write register contains the current value of the year counter.
This register can be read at any time without affecting the counter count.
Writing to this register loads the value to the year counter and the
counter continues to count from this new value.
The value stored in this register is a two’s complement representation of
the year, relative to 2000. For example, the year 2008 is represented
by 8 ($08), and the year 1979 is presented by –11 ($F5). The range of
this register is only valid for –99 to +99. Writing a value other than –99
to +99 to this register has no effect.
