INTRODUCTION (Continued)
and out of memory through the Host’s bus.
A
possible system configuration for the MK50H27 is
shown in figure 1.
For added flexibility a transparent mode provides
an HDLC transport mechanism without link layer
support. In this mode no protocol processing is
done, all data received between opening flag and
CRC is written to the shared memory buffer and it
is up to the user to take care of the upper level
software.
The MK50H27 may be used with any of several
popular microprocessors, such as: 68040 ...
68000, 6800, Z8000, Z80, 80486 ... 8086, i960,
etc.
The MK50H27 may be operated in either full or
half duplex mode. In half duplex mode, the RTS
and CTS modem control pins are provided. In full
duplex mode, these pins become user program-
mable I/O pins. All signal pins on the MK50H27
are TTL compatible. This has the advantage of
making the MK50H27 independent of the physical
interface. As shown in figure 1, line drivers and
receivers are used for electrical connection to the
physical layer.
