I am a newer on freescale 8-bit MCU. I know that all unused modem GPIOx should programmed as outputs in the low state when the MCU goes to Hibernate or Doze modes according to the document MC1321x.pdf on page 65. My question is that how can I operate on it, I have not seen any register about GPIO from any documents. I also check MC13213.h created automatically by Coderwarrior, but I have found nothing on it either.
Can anyone help me? Thank you very much!
