Port S general purpose input/output data—Data Register, SCI TXD, PWM channel7
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, PWM channel6
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 input data—
This register always reads back the buffered state of the associated pins. This can also be used to detect overload
or short circuit conditions on output pins.
• The SCI takes precedence over the PWM7 and general purpose I/O function if enabled
• The PWM7 takes precedence over the general purpose I/O function if enabled
• The SCI takes precedence over the PWM6 and general purpose I/O function if enabled
• The PWM6 takes precedence over the general purpose I/O function if enabled
