Port 5 analog inputs disturb protection
A Schmitt trigger protection can be activated on each pin of Port 5 by setting the dedicated
bit of register P5DIDIS. This allows the input leakage effect to be reduced.

Port 6
Port 6 is an 8-bit port. If it is used for general purpose I/O, the direction of each line can be
configured via the corresponding direction register DP6. Each port line can be switched into
push-pull or open-drain mode via the open-drain control register ODP6. In the ST10F296E,
SSC1 is implemented on pins P6.5, P6.6, and P6.7. When the module is enabled through
the XPERCON register, the corresponding bits P6, DP6 and ODP6 are overwritten by the
new XSSCPORT register (mapped on the XBus). This allows the user to program pins P6.5,
P6.6, and P6.7 according to the SSC1 configuration.
