If the low-order bank (0) is specified by the 8-bit data (the second byte of the display character control

command) of the character data, character addresses 00H through FFH (common addresses 000H through

0FFH) of the low-order (0) bank are specified. If the high-order bank (1) is specified, character addresses 00H

through FFH (common addresses 100H through 1FFH) of the high-order (1) bank are specified.

If FEH is specified at the character address of the display character control command for both banks, the

command can be used as the Display Off code. If FFH is specified, it can be used as a 2-byte successive

command end code.
