5.1
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 15
,
Table 16
, and
Table 17
. 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 Power PC family of microprocessors. (For using a Motorola 68K asynchronous
processor, see
Figure 60
and
Table 21
)
Table 15
lists and describes those microprocessor interface signals
whose role is constant across the two modes.
Table 16
describes the role of some of these signals when the
microprocessor interface is operating in the Intel mode. Likewise,
Table 17
describes the role of these signals
when the microprocessor interface is operating in the Motorola Power PC mode.

Microprocessor Interface Mode Select Input pins
These three pins are used to specify the microprocessor interface mode. The relationship
between the state of these three input pins, and the corresponding microprocessor mode is
presented in
Table 14
.

Three-Bit Address Bus Inputs
The 3 MSBs of the address bits are used as a chip select decoder. The state of these 3 pins
enable the Chip Selects for additional LIU devices.

Eight-Bit Address Bus Inputs
The XRT83SH314S LIU microprocessor interface uses a direct address bus. This address bus
is provided to permit the user to select an on-chip register for Read/Write access.

Chip Select Input
This active low signal selects the microprocessor interface of the XRT83SH314S LIU and

Address-Latch Enable:
This active high signal is used to latch the contents on
the address bus ADDR[7:0]. The contents of the address bus are latched into the

Read Signal:
This active low input functions as the read signal from the local

P.
When this pin is pulled “Low” (if CS is “Low”) the LIU is informed that a read oper-
ation has been requested and begins the process of the read cycle.

Write Signal:
This active low input functions as the write signal from the local

When this pin is pulled “Low” (if CS is “Low”) the LIU is informed that a write
operation has been requested and begins the process of the write cycle.

Ready Output:
This active low signal is provided by the LIU device. It indicates
that the current read or write cycle is complete, and the LIU is waiting for the next
command.
