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 11
,
Table 12
, and
Table 13
. 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 34
and
Table 15
)
Table 11
lists and describes those microprocessor interface signals whose role is
constant across the two modes.
Table 12
describes the role of some of these signals when the microprocessor
interface is operating in the Intel mode. Likewise,
Table 13
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 10
.

Eight-Bit Address Bus Inputs
The XRT83VSH28 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 XRT83VSH28 LIU and
enables Read/Write operations with the on-chip register locations.

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
ADDR[7:0] inputs on the falling edge of ALE.

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

P.
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.
