So, why have X modes to do with up/down and Y with left/right?WikiTI wrote:# 04 : Set X auto-decrement mode. Every read or write operation from the data port will cause the LCD's internal pointer to move up one row.
# 05 : Set X auto-increment mode. Every read or write operation from the data port will cause the LCD's internal pointer to move down one row. The TI-83+ expects the LCD to be in this mode for most display routines.
# 06 : Set Y auto-decrement mode. Every read or write operation from the data port will cause the LCD's internal pointer to move left one column.
# 07 : Set Y auto-increment mode. Every read or write operation from the data port will cause the LCD's internal pointer to move right one
How can that be true?
afaik, either one of the things it says in each line can be true, either 04 is X auto-decrement mode or "Every read or write operation from the data port will cause the LCD's internal pointer to move up one row".
Could someone explain this?
