This read/write register contains the current value of the second counter.
This register can be read at any time without affecting the counter count.
Writing to this register loads the value to the second counter and the
counter continues to count from this new value.
The second counter rolls over to 0 ($00) after reaching 59 ($4B). Writing
a value other than 0 to 59 to this register has no effect.
This read/write register contains the current value of the minute counter.
This register can be read at any time without affecting the counter count.
Writing to this register loads the value to the minute counter and the
counter continues to count from this new value.
The minute counter rolls over to 0 ($00) after reaching 59 ($4B). Writing
a value other than 0 to 59 to this register has no effect.
