June 7, 2012
The Enable bit (DSTE) is in the Month forward register, so the BCD
value for that register is altered with the additional bit. The Week
and Day values along with Week/Day vs Date select bit is in the
Week/Day register, so that value is also not straight BCD. Hour and
Month are normal BCD, but the Hour doesn’t use the MIL bit since
Military time PM values are already discretely different from
AM/PM time PM values. The DST reverse setting utilizes the option
to select the last week of the month for October, which could have
4 or 5 weeks but needs to have the time change on the last
Sunday.
Note that the DSTADJ bit in the status register monitors whether
the DST forward adjustment has happened. When it is “1”, DST
forward has taken place. When it is “0”, then either DST reverse
has happened, or it has been reset either by initial power-up or if
the DSTE bit has been set to “0”.
