The [[7854]] contains a microprocessor controlled 40x16 character display generator which is also used to display plugin readout. The readout interface therefore contains only the column driver, multiplexer and A/D section but not the character generator - it only feeds readout data to the microprocessor. | The [[7854]] contains a microprocessor controlled 40x16 character display generator which is also used to display plugin readout data.
