13.7.5 TOD Minutes Counter (TODMIN)
When TODEN is set, this counter is continuously updated to contain the current minutes value.
The value of the counter can be read through the corresponding minutes latch, but it cannot be
modified. When TODEN is cleared, TOD counting is disabled and this counter can be modified.
When TODEN is set to one again, the counting resumes from the new set time.
