Power Control & GPIO pins

2004-08-09 by Leighton Rowe

I heard that pull ups are needed to run P0.2 & 3 as regular GPIO 
pins, since they are part of the I2C interface. Given the board I'm 
working with...I might not have the luxury to make that hardware 
change.

Isn't there another way (without using pull ups)? How about 
disabling the I2C interface in the Power Control Register (PCONP)? I 
haven't tried it as yet, but if anyone else did, I wouldn't mind 
hearing from you on how it went. 

Thanks in advance,
Leighton
