• Setting the source oscillation frequency
conditions
• Valid only for 1/19 duty
1 0 0 X 0 0 0 1/0 • Switching between display addresses 0 to
15, and 16 and 31
1 0 0 X 0 0 1 1/0 • VLCD adjustment, 8 stages
• Released by setting DO = 1
independently of the H/L of the C/D
1 0 0 X 0 1 0 0 • Oscillation suspension and DISPOFF
instruction
• Switching output and high impedance of
1 0 0 X 0 1 1 1/0 SO
• On when DO = 1, and off when DO = 0
• Continued OSC
1 0 0 X 1 0 0 1/0 • All COM and SEG are at VDD level when
turned off
• Pointer address is incremented by one
1 0 0 X 1 X 1 X • The relative operation with with (I1, I0)
is exceptional.
• Character and arbitrator blinking is
0 X X X 0 0 0 X controlled. The arbitrator is based on
the 5-dot unit.
• For the arbitrator, blink setting is
0 X X X 0 0 1 X accepted even if all 5 dots are displayed
in blinks, but blinking does not occur.
0 X X X 0 1 0 X • Cursor on
0 X X X 0 1 1 X • Cursor off
• Cursor blinking is controlled. If the
0 X X X 1 0 0 X cursor display not specified, blink
setting is accepted, but blinking
0 X X X 1 0 1 X does not occur.

1. Commands number 1 to 8, do not affect pointer address.
2. When commands from 9 to 17 and display code data are input, the pointer address
is automatically incremented by one (1).
