DE2 - CFAH1602B-TMC-JP Initialization Sequence

Hello,

I have a Terrasic DE2 and am trying to initialize the LCD and then turn on the backlight for confirmation.

I've modeled the sequence all the way up to the final point described in the datasheet (link to datasheet (https://drive.google.com/file/d/0b5za7izq3qsrrxj2vklhu3zwrku/view?usp=sharing)), using an FSM. I cannot understand the last state, where it looks like I am to write four different instructions.

Section 14 (page 17/20) describes the initialization procedure:

1. LCD_ON = 1

2. Wait > 15ms

3. LCD_RS = 0, LCD_RW = 0, LCD_DATA = 0x30

4. Wait > 4.1ms

5. LCD_RS = 0, LCD_RW = 0, LCD_DATA = 0x30

6. Wait > 100us

7. LCD_RS = 0, LCD_RW = 0, LCD_DATA = 0x30

8. This is where my problems begin

At step 8, I am to send 4 instructions, but am not sure how to do it, how long I am to wait in between sending instructions, and if it's a read or a write etc.... :confused::oops:

Could someone help me understand what I need to do next?
