Technical Reference

faster than normal I/O access.

All messages and data are transferred through this 512 KB dual-ported memory. The buffer area appears as normal 16-bit memory to the PC AT I/O channel.

Every Intellio C218Turbo/PCI only occupies 16 KB of memory space (window) from the system point of view.

UART 16C550C

The UART chip, 16C550C, is an intelligent asynchronous controller capable of supporting one full duplex channel that transfers data at 921.6 Kbps simultaneously. To increase the overall data throughput, special features such as on-chip FIFO and on-chip hardware flow control are used to reduce the number of interrupts to the on board CPU and to prevent any loss of valuable data.
