CLS=”H” : Internal oscillator circuit is enabld
CLS=”L” : Internal oscillator circuit is disabled (requires external input)
When CLS=”L”, input the display clock through the CL terminal.
This terminal selects the master/slave operation for the NJU6676. Master
operation outputs the timing signals that are required for the LCD display,
while slave operation inputs the timing signals required for the LCD,
synchronizing the LCD system.
