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 alternate function (CS) is selected automatically in this case.
Note: The open drain output option can only be selected via software earliest during the initialization

12.9 - Port 7
If this 8-bit port is used for general purpose I/O, the direction of each line can be configured via the corre-
sponding direction register DP7. Each port line can be switched into push/pull or open drain mode via the
open drain control register ODP7.
routine; at least signal CS0 will be in push/pull output driver mode directly after reset.
