DS1260 Programming Question

Has anyone ever had an issue setting the low limit temperature of
the DS1620 thermostat chip? I can program the high limit and config as well as
read the high limit, low limit, and temperature. I use the same code
module to program the high limit (TH) and the low limit (TL), but it
doesn't seem to work on the low limit. The low limit is "stuck" on 0x20, the default
value. I've cycled the temperature and the Thigh, Tlow, and Tcom pins all behave as
they should. I tried two other chips and it behaves the same way. I can hit the chip with
a can of freeze to test the low limit, and it is indeed set to the default value (10 degC/50 degF).
It seems to be behaving like I'm using the wrong programming code (0x02), however I'm using the proper code as
documented in the spec sheet as well as in your app note, and every other code sample
I've looked at. I'm sure I have a still have a bug, but I'm stumped!!
BTW I'm using an Arduino and the Arduino IDE and c++ to program the chip.
(Perhaps not the right forum but there seemed to be more DS1620 activity here.)
