TABLE 1.  LCD Command 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.
