Note) 1. The OE pin should be set low each time the display is changed.
2. If the fluorescent display control input (OE) is set low during a serial data transfer, the MN12511 will detect an
incorrect transfer and output the V_PP level from all the high-voltage output ports.

Note) 1. These values are limiting values under which the device will not be destroyed. Operation is not guaranteed within these
ranges.
2. These values are limiting values such that the device will not be destroyed if voltages within these ranges are applied to the
pins. Operation is not guaranteed within these ranges.
3. Applies to any 100 ms period.
