Hi all

I was intend to use an MAX3100 - spi-uart in my AT89LS53-appl.
After a while when I started to understad this MAX- circuit, I was
re-configured the spi-con-register in the cpu, (SPCR).
What I did, was that I change the CPOL (clock polarity).
It seems to work with the uart, but it looks like it was the last
time it works to reprogram that AT89LS53-Flash.

So what I obviously have to do, ---when I change the uP---, is to
use the 'positive clock-pulse' only when I work with the SPI-UART,
and then change the CPOL direct back again after uart-work.

I'm sooo happy for that discovering.
We have discuss this problems a several of times erlier on this board.

There is no options to change that in the equinox - programmer..!!
