ARE TOU SHURE???
I did A DESIGN not LONG AGO using a MSP430F1101
and ANOTHER with MSP430F413 and yes my LCD was also 5v
I burned both chips when i tried tu pull'em up at 5V..
I couldn't programme them any more ...
once i designed just using 3v no more problems
the data sheet specifies a VOH por the Output ports MAX = VCC
and the VCC MAX = 3.6 .. some place i read that they will withstand 4.1 Volt .. and to get a BETTER contrast in my LCD (5 volt) i had supplied the chip with 3,9 v ..and no damage ... There is an APP NOTE on how to
interface those chips to 5V.. But they don't mention 5v pull ups ..
don't do it
