THE MICROPROCESSOR INTERFACE BLOCK SIGNALS
The LIU may be configured into different operating modes and have its performance monitored by software
through a standard microprocessor using data, address and control signals.
These interface signals are
described below in Table 16, Table 17, and Table 18. The microprocessor interface can be configured to
operate in Intel mode or Motorola mode. When the microprocessor interface is operating in Intel mode, some
of the control signals function in a manner required by the Intel 80xx family of microprocessors. Likewise, when
the microprocessor interface is operating in Motorola mode, then these control signals function in a manner as
required by the Motorola microprocessors.
(For using a Motorola 68K asynchronous
processor, see
Figure 30 and Table 20) Table 16 lists and describes those microprocessor interface signals whose role is
constant across the two modes. Table 17 describes the role of some of these signals when the microprocessor
interface is operating in the Intel mode. Likewise, Table 18 describes the role of these signals when the
microprocessor interface is operating in the Motorola Power PC mode.
