Segment driver outputs.
The S59/COM10 and S60/COM9 pins can be used as
common driver outputs under the “set display technique”
instruction.

RESETB
77(75) Reset signal input.
• When RESETB is low (VSS):
• Display off
S1 to S58 = “L” (VSS).
S59/COM10 and S60/COM9 = “L” (VSS).
COM1 to COM8 = “L” (VSS).
• Serial data transfer is disabled.
L
I
• The OSCI/OSCO pin oscillator is stopped.
• When RESETB is high (VDD):
• Display on after a “display on/off control” (display
on state setting) instruction is executed.
• Serial data transfers are enabled.
• The OSCI/OSCO pin oscillator operates.
