TABLE 1. LCD Command and Character Codes
Command codes are used for LCD setup and control of character and cursor position. All
command codes are written to LCD panel address $B5F0. The BUSY flag (bit 7) should be
tested before any command updates to verify that any previous command is completed. A
read of the command address $B5F0 will return the BUSY flag status and the current display
character location address.
