Freescale Semiconductor
= Input, high impedance
= Input, internal pull-up enabled
= Analog input, high impedance, tie to ground if not used
= Control, always connect
= Connect if using internal oscillator
= 0V
= 2.5V supply
= 5V supply
= ATD reference

Pin States Following Reset in Normal Single Chip Mode
= Pin has key wake-up capability
= Internal pull-downs active only during reset
= Pin is sampled at reset for oscillator selection
= Pin always has internal pull-up
= Pin is ECLK output in special modes
