44 pins are dedicated to frontplane and backplane drivers; on the 64-pin package, 36 pins are dedicated.
Immediately after reset, the LCD driver pins are high-impedance. For detailed information about LCD
frontplane and backplane driver pins, see the LCD chapter.
2.3.7
MC9S08LC60 Series MCUs support up to 24 general-purpose I/O pins which are shared with on-chip
peripheral functions (timers, serial I/O, ADC, keyboard interrupts, etc.). On each MC9S08LC60 Series
device, there is one input-only and two output-only port pins. When a port pin is configured as a
general-purpose output or a peripheral uses the port pin as an output, software can select one of two drive
strengths and enable or disable slew rate control. When a port pin is configured as a general-purpose input
or a peripheral uses the port pin as an input, software can enable a pullup device. For information about
controlling these pins as general-purpose I/O pins, see
Immediately after reset, all pins that are not output-only are configured as high-impedance
general-purpose inputs with internal pullup devices disabled. After reset, the output-only port function is
not enabled but is configured for low output drive strength with slew rate control enabled. The PTC6 pin
defaults to BKGD/MS on any reset.

To avoid extra current drain from floating input pins, the reset initialization
routine in the application program should either enable on-chip pullup
devices or change the direction of unused pins to outputs so the pins do not
float.
