I have an Advanced Transdata emulator which looks at a DS1302. It is OK on
the emulator but not on the chip itself. Every other function is ok. The
time and data are correct when I read it out with the emulator. When I blow
a chip I find the results are consistent but not correct. I slowed down the
routines dramatically (200mS between all signal changes!!) but still the
same. The emulator differences are that MCLR is not active and the emulator
uses it's own clock. In addition the emulator has a ribbon cable. Has
anyone noticed anything like this?

TIA,
