Hi Fabio,

If you want to write in this form, it should be "1 * 32 + 31".

Can you add #defines to describe the weim registers ? Thius is helpful
for MX51, too.

A macro to set the single chip select is better, something as
CS_SET_SIZE(chipselect, size), or something like that. What do you think
about it ?
