Data Sheet
With ODP6.x = ‘1’ (open drain output selected), the internal pullup device will not be
active during Hold mode; external pullup devices must be used in this case.
When entering Hold mode the CS lines are actively driven high for one clock phase, then
the output level is controlled by the pullup devices (if activated).
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 alternate function (CS) is selected
automatically in this case.
Note: The open drain output option can only be selected via software earliest during the
Figure 40
initialization routine; at least signal CS0 will be in push/pull output driver mode
directly after reset.
