Displays the specified line in black-and-white form. The specified line corresponds to the address line of DDRAM.
Display the specified line of the DDRAM in black-and-white form by setting LB4 to LB1. Blinking is performed at
the same frequency as cursor blink. If blinking is caused to occur at the same time, the cursor position will be hard
to know.
LB4 = 0: displays the data for line 4 of the DDRAM in standard form (no blink)
(DDRAM 60H to 6FH)
= 1: displays the data for line 4 of the DDRAM in black-and-white reverse blink form
(DDRAM 60H to 6FH)
LB3 = 0: displays the data for line 3 of the DDRAM in standard form (no blink)
(DDRAM 50H to 5FH)
= 1: displays the data for line 3 of the DDRAM in black-and-white reverse blink form
(DDRAM 50H to 5FH)
LB2 = 0: displays the data for line 2 of the DDRAM in standard form (no blink)
