Port E general purpose input/output data—Data Register, ECLKX2 output
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.

The associated pin can be used as general purpose I/O. In general purpose output mode the register bit value is
driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
ECLKX2
• The ECLKX2 output function takes precedence over the general purpose I/O function if enabled.
