Low voltage I/O for MPC555

Hello,
Are there any ports that can be used for I/O which are low voltage 
(i.e. less than 5 volts). Currently I am using GPIO (address: 0x306100) 
port but I dont see any option to use this in low voltage mode. I am 
interfacing this micro with an LCD which requires at most 3.3V for the 
data lines. I would like to connect directly to the LCD instead of 
using bus transceiver chips. Thanks for the help.
