Port S general purpose input/output data—Data Register
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.
Port S general purpose input/output data—Data Register, SCI TXD 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.
Port S general purpose input/output data—Data Register, SCI RXD input
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 SCI function takes precedence over the general purpose I/O function if enabled.
• The SCI function takes precedence over the general purpose I/O function if enabled.
