OLED LCD Code Problems

[freeskier89]

Hello,

I am writing some assembly to control a LCD with a SSD1339 controller with a 8bit 6800 parallel interface. The timing diagram for the communication is here on page 56.
(Datasheet: https://www.electro-tech-online.com/custompdfs/2007/05/SSD1339_17.pdf)

I have looked through the datasheet and it looks pretty straight forward, but I can't seem to get the LCD to turn on. Early in the datasheet it said that it uses the Enable pin as a latch for the data, but the timing suggests that it is CS# instead? Here are the essential elements for the LCD that I have written:

LCD_C MACRO X
	MOVLW X
	CALL LCD_WriteCommand
	ENDM
LCD_D MACRO X
	MOVLW X
	CALL LCD_WriteData
	ENDM
LCD_WriteData
	BSF	port_lcdctrl,lcd_DC
	CALL LCD_WriteByte
	RETURN
LCD_WriteCommand
	BCF	port_lcdctrl,lcd_DC
	CALL LCD_WriteByte
	RETURN
LCD_WriteByte

	;This is a mess... I hooked up the D7 to D0 (mcu) backwards to the LCD
	;hence I have to reverse the order of the byte. 
	;TODO: THINK OF A MORE EFFICIENT WAY OF DOING THIS!
	MOVWF lcd_buffer

	CLRF 	lcd_buffer1
	
	BTFSC   lcd_buffer, 0
	BSF     lcd_buffer1, 7
	BTFSC   lcd_buffer, 1
	BSF     lcd_buffer1, 6
	BTFSC   lcd_buffer, 2
	BSF     lcd_buffer1, 5
	BTFSC   lcd_buffer, 3
	BSF     lcd_buffer1, 4
	BTFSC   lcd_buffer, 4
	BSF     lcd_buffer1, 3
	BTFSC   lcd_buffer, 5
	BSF     lcd_buffer1, 2
	BTFSC   lcd_buffer, 6
	BSF     lcd_buffer1, 1
	BTFSC   lcd_buffer, 7
	BSF     lcd_buffer1, 0
	
	;make sure reset is high (not resetting). I have heard that some
	;people have troubles with pins randomly falling low.
	BSF port_lcdctrl, lcd_RES

	; Move Byte onto portD
 	MOVF 	lcd_buffer1, w
 	MOVWF	port_lcddata
	
	BSF 	port_lcdctrl, lcd_E
 	BCF 	port_lcdctrl,lcd_Rw

	BCF 	port_lcdctrl, lcd_CS

	CALL 	DLYMS
	
	BSF 	port_lcdctrl, lcd_CS
	
	CALL 	DLYMS

	BCF 	port_lcdctrl,lcd_E
	BSF 	port_lcdctrl,lcd_Rw
	BSF 	port_lcdctrl,lcd_DC
	
	RETURN
LCD_Init
	
		CLRF port_lcddata
	BSF port_lcdctrl, lcd_E
	BCF port_lcdctrl, lcd_DC
	BCF port_lcdctrl,lcd_Rw

  	CALL LCD_Reset
	
	LCD_C h'A0'
	LCD_D b'01100000' ;Configure color settings

 	LCD_C h'BB'
	LCD_D h'1C'
	LCD_D h'1C' 
	LCD_D h'1C'
	
  ; // Set VcomH

  	LCD_C h'BE'
	LCD_D h'1F'
	
  ; // Set contrast current for A B C
  ; // Color A
  ; // Color B
  ; // Color C
 	LCD_C h'C1'
	LCD_D h'AA' 
	LCD_D h'B4' 
	LCD_D h'C8' 
	
  ; // Set master contrast
  ; // no change
  	LCD_C h'C7'
	LCD_D h'0F' 
	
  ; // Duty
  ; // 127+1
  	LCD_C h'CA'
	LCD_D h'7F'
	
 ; // Display on
	LCD_C h'AF'
	
	RETURN

I'm quite sure that I have the hardware end hooked up correctly and it is something slightly wrong with my code. My guess is that it is either the way I am setting the control pins for writing to the LCD or the initialization parameters. I would be deeply grateful if anyone could lend some expertise!

Edit: There isn't anyway to remap a port in MPLAB is there? That would be a nice software feature to have (to take literals and rearrange them).
