* At this time, normal mode (scanning with 1 pulse) is set when MODE1 = "H" and MODE2 = "H",
jumping 2-pulse mode (scanning with 2 pulses) is set when MODE1 = "H" and MODE2 = "L",
continuous 2-pulse mode (scanning with 2 pulses) is set when MODE1 = "L" and MODE2 = "H", and
output VEE level is set when MODE1 = "L" and MODE2 = "L".
