Had you read through the entire tutorial, you'd have realized what all those definitions represent, and how they work together to meet the requirements of the LCD interface. It would have made more sense, then.

Go ahead and read the thing from beginning to end, understanding what all that stuff means.

Then go back and read the instructions, particularly the syntax and pseudo-op's of your assembler, and understand what they are and do. After that, get out the datasheet for the MCU you're using, and figure out what the timing resolution capabilities of that MCU are, in terms of its instruction set.

When you've done that, go back and re-read the spec's for your particular LCD (You do have those, don't you? Some of them deviate considerably from the mean.)

Having done that, you'll be prepared to attack this problem. It's a lot of work, but once you've attacked this problem and successfully completed it, the next one will be easier.
