The chip select lines of Port 6 have an internal
weak pull-up device. This device is switched on
during reset. This feature is implemented to drive
the chip select lines high during reset in order to
avoid multiple chip selection.
After reset the CS function must be used, if
selected so. In this case there is no possibility to
program any port latches before. Thus the
