When i use cube ice and 21x34 pod practice modify IO port,
Pod only connect P17 to voltage meter, no other external component.
the code make me confuse. (PS. Designer 5.0)
------------------------------------------------------------------------------------------------
PRT0GS &= ~0x08; //disconnect from global bus
PRT0DM2 |= 0x08;
PRT0DM1 &= ~0X08; //DM[2:0]=100, Slow strong high, high-z low
PRT0DM0 &= ~0x08;
PRT0DR &= ~0x08;
PRT3GS &= ~0x02; //disconnect from global bus
PRT3DM2 |= 0x02;
PRT3DM1 &= ~0x02; //DM[2:0]=100, Slow strong high, high-z low
PRT3DM0 &= ~0x02;
PRT3DR |= 0x02;

P17 is modified to low normally,
then modify P31 ,
P17 become high.....
Can any one tell me why ? please.
=====================================================
I forget the P17 and P31 both connect to analog bus....
Forget my stupidity.
