HP E1399A Description
The HP E1399A Breadboard Module is a B-size register-based device that
provides a convenient interface to a VXI mainframe backplane. It allows
you to construct your own custom hardware for use with the mainframe.
General Module
Features
The module is supplied with all interface components loaded and soldered.
Your VXI mainframe can communicate with this module configured as an
A16/D16 device. The breadboard module interface circuitry is implemented
and accessible according to the requirements outlined in the VXIbus
Specification.
Users can still provide custom extensions to expand module addressing
capability to A24 or A32 by adding appropriate circuitry according to the
VMEbus and VXIbus specifications.
Backplane Interface
Features
An overview of the HP E1399A interface features follows. Figure 1-1
shows a block diagram of this interface.
Note
For hardware operation, a mnemonic suffixed with an asterisk (such as
WRITE*) indicates inverse logic (0 or low = true; 1 or high = false). A high
state (1) is defined as a positive voltage (u5 V) and a low state (0) is
defined as zero V (ground) at the specified signal point.
The HP E1399A interface features are:
•
Address Lines and Register Decoding. The module implements 15
address lines (A1-A15) to allow for: 1. decoding one of 255
switch-selectable logical device addresses in the upper fourth of the
A16 VME address space, and 2. selecting one of the breadboard
configuration registers for read/write operations. The module
decodes the Address Modifier lines AM0-AM5 and acts on codes
29
16
and 2D
16
only.
•
Data Lines. Data lines D0-D15 are available for use on the
Breadboard module. These 16 lines are buffered by data bus drivers
and used for writing to, and reading from, the configuration registers
(Status, ID, Device Type, and Control) via an internal data bus
(DB0-DB15).
