I just got reply from Noritake, they say that WR and CS should follow each other

The modified code is below. I haven't tested this yet as I am at work and don't
have this home project in front of me.

#DEFINE WR PORTC,0
#DEFINE CS PORTC,1
#DEFINE BUSY PORTC,2
                                                                                
        ; Takes the contents of character and displays it.
                                                                                
DISPLAYCHAR
        ; wait for BUSY to be low...
WAITBUSY
        BTFSC BUSY
        GOTO WAITBUSY

        BCF CS    ;This is from the email from Noritake

        ; lower WR
        BCF WR
                                                                                
        ; Load  data
        MOVFW character
        MOVWF PORTB
                                                                                
        ; raise wr
        BSF WR

        BSF CS   ;This is from the email from Noritake

        RETURN

I hope this works out, the data sheet is painfully ambiguous, even as far as
saying 'Don't care' in the truth table regarding it, and a double line in the
timing chart.

Note that this is _not_ used for serial communication. I will test it out 
tonight and report my findings

Thanks for the suggestions guys (especially Jan Erik)
