Introduction
The VMIVME-1160A is designed with standard Change-of-State (COS) control and
interrupt logic that detects any COS and provides an interrupt vector to the byte level.
It incorporates an Epic Ei68C153 Bus Interrupter Module (BIM) supporting interrupts
on any of seven levels.
Each byte (8 bits) of input may have a unique interrupt vector that is generated upon
a COS in any bit of that byte. The board also has an Interrupt Enable Register which
allows interrupts to be enabled on a byte-by-byte basis. The input data may be
accessed as a D8 or D16 transfer.
A functional block diagram of this product is shown in Figure 1 on page 12.
Interrupts are generated on any COS (positive or negative transition). Polarity is
determined by reading the input port after the COS interrupt.
NOTE: State changes that occur during the interrupt processing window (internal
request to interrupt acknowledge cycle complete) will not be detected. The time
between user input state changes must not be less than the computer interrupt
processing time; otherwise, the state changes will be lost.
A Change-of-State Application Guide that describes the complete COSMODULE™
product line, VMIC's Document No. 825-000000-002, is available from VMIC. A
summary of the COSMODULE™ product line is provided in Table 1, “Cosmodule™
Product Line Summary,” on page 13 for a list of reference.

Motorola MC68153 BIM
The VMIVME-1160A was originally manufactured using the Motorola MC68153 BIM,
which is now out of production. The Epic Ei68C153 BIM is being used as a
replacement on all newly-manufactured VMIVME-1160A boards. Any references to
the Ei68C153 in this document are also applicable to the MC68153.

Introduction
Block Diagrams
The VMIVME-1160A consists of eight functional building blocks as illustrated in
Figure 1-1 on page 18. The eight sections of the VMIVME-1160A are:
1. Address Logic
2. Control Logic
3. Data Logic
4. Bus Interrupter Module (BIM) Logic
5. Interrupt Enable Logic
6. Change-of-State Detection Logic
7. Input Data Registers
8. Input Buffers
Each section of the design is illustrated in further detail in Figure 1-2 through
Figure 1-10 starting on page 19.
Interrupt Functions
Interrupts are generated on any Change-of-State (positive or negative transition). The
polarity is determined by reading the input port after a Change-of-State interrupt
occurs. The data transfer bus, the arbitration bus, and the interrupt bus are all used in
the process of generating and handling bus interrupts.
NOTE: State changes that occur during the interrupt processing window (internal
request to interrupt acknowledge cycle complete) will not be detected. The time
between user input state changes must not be less than the computer interrupt
processing time; otherwise, the state changes will be lost.
The reader should refer to "The VMEbus Specification" for a detailed explanation of
the priority interrupt bus. See “Reference Material List”on page 14.
