The output level is selected among V
combination of FR signal and RAM data
Reverse mode
Located at both side of segment drivers, used for edge
display.
The output level is selected among V
the combination of FR and scan data.
Open when using internal oscillator clock or used as slave
device.
In this case, OSC
Connect external oscillating source to OSC
resistor between OSC
