DESCRIPTION
converter, timers, DMA controller, interrupt controller, etc., are integrated in a single chip.
V55PI provides a migration path from the V25. It offers higher-level functions and higher performance, and is particularly
suitable for control of data processing systems associated with mechanical control, including printer and facsimile.
