When a Rabbit microprocessor is configured as a slave, parallel port A and certain other
data lines are used as communication lines between the slave and the master. The slave
unit is a Rabbit configured as a slave. The master can be another Rabbit or any other type
of processor. Rabbits configured as slaves can themselves have slaves.
The master and slave communicate with each other via the slave port. The slave port is a
physical device that includes data registers, a data bus, and various handshaking lines. The
slave port is a part of the slave Rabbit, but logically it is an independent device that is used
to communicate between the two processors. Figure 13-1 shows a diagram of the slave port.
