When use built -in switching circuit and
generate VEE, VEO pin connect to VEEL, R
pins. VM voltage is point of reference and
reversed and output the voltage input to the
voltage between VLCD and VM. If built-in
switching circuit is not used, don't connect
any lines to this pin.

Input
This pin specifies the cycle of the alternating
signal (M signal) in the unit of the number of
lines. The number of lines, which is an
integer from 2 to 31, is specified as follows.
Usually, specify the number of lines within a
range from 10 to 31. When the HD66131T is
driven by an external alternating signal,
specify the number of lines as zero.
