Hello everyone.  I'm using MC9S12P64 Micom.


 If there are unused pins in application, What is best way to handle it ?


For example,


 Configure data direction register output and set data register '0' (floating, do not need to connect)


 Configure DDR input and tie to gnd or Vdd with Internal Pull-up register


If there are documents I can refer to, it is welcome.

(I found AN2727 about HCS12 D-family but I can not find about MC9S12P-family)


Thanks for your reply.
