Sets display row and moves cursor to char column 1. The low order nibble of rr
designates the display row. Bit 5 of rr specifies a Double High row. For example: rr =
0Eh would select display row 14. rr = 23h would select display row three, Double
High.
Sets the physical row, where the low order nibble of rr designates the physical row.
rr can be any value from 00h to 0Fh.
Places the cursor at the character column position designated by cc, which can be
any value from 00h to 20h (column 0-32). Zero is the PAC space.
Writes the data byte dd to the current cursor location and then increments the cursor.
Maps the current physical row to the display row designated by the low nibble of the
rr byte. Bit 4 of rr = 1 enables display of the row. Bit 5 of rr = 1 indicates a Double
High row.
Same as A3 command but specifies a Double Wide character.
Sets the RDY bit of SS and then suspends serial command execution for
approximately the number of frames designated by the nn byte.
Sets the Graphics Character set in force.
Sets the Extended Character set in force.
