ST10F280
While an external bus mode is enabled, the user software should not write to the port output latch, other-
wise unpredictable results may occur. When the external bus modes are disabled, the contents of the
direction register last written by the user becomes active.

12.4 - Port 2
If this 16-bit port is used for general purpose I/O, the direction of each line can be configured via the cor-
responding direction register DP2. Each port line can be switched into push/pull or open drain mode via
the open drain control register ODP2.
