42 Hardware
Use of the Serial Ports
If you plan to use the serial ports extensively, or if you intend to use syn-
chronous communications, Rabbit Semiconductor recommends that you
obtain copies of the following Zilog technical manuals, available from
Zilog, Inc, in Campbell, California.
Each serial port appears to the CPU as a set of registers. Each port can be
accessed directly with the
the symbolic constants shown in Table 3-2.
