It should be adequate for an 8-digit (7-segment) triplexed or quadplexed display if it is compatible with bias and voltage specifications. | |

Generally it will consist of setting up the peripheral, connecting it correctly to the display and anything else required and writing a '1' or '0' in some on-chip bits where you want the segment to be in one state or the other. Those bits will probably be scrambled. | |
