Chapter 2 Pins and Connections
When an on-chip peripheral system is controlling a pin, data direction control bits still determine what is
read from port data registers even though the peripheral module controls the pin direction by controlling
the enable for the pin’s output buffer. For information about controlling these pins as general-purpose I/O
pins, see
The MC9S08SG32 Series devices contain a ganged output drive feature that allows a safe and reliable
method of allowing pins to be tied together externally to produce a higher output current drive. See

Pin Number
To avoid extra current drain from floating input pins, the reset initialization
routine in the application program should either enable on-chip pull-up
devices or change the direction of unused pins to outputs so they do not float.
When using the 20-pin devices, either enable on-chip pullup devices or
change the direction of non-bonded PTC7-PTC4 and PTA7-PTA6 pins to
outputs so the pins do not float.
When using the 16-pin devices, either enable on-chip pullup devices or
change the direction of non-bonded out PTC7-PTC0 and PTA7-PTA6 pins
to outputs so the pins do not float.
