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.
