2.3.2.1 Transmit Information (Info) Word

The following bits describe the Transmit Information word contents.

Bit

Number

Mnemonic

Description

15-11

WC(4:0)

Word Count Bits. These five bits contain word count information extracted from the

receive command word bits 15 to 19.

10

N/A

Not Applicable.

9

CHA/B

Channel A/B. Assertion of this bit indicates that the message was received on the A bus.

Conversely, if this bit is set to logic zero, the message was received on the B bus.

8

N/A

Not Applicable.

7

ME

Message Error. Assertion of this bit indicates a message error condition was observed

during processing. See bits 0 to 4 for more detail.

6-5

N/A

Not Applicable.

4

ILL

Illegal Command Received. Assertion of this bit indicates the command received was an

illegal command.

3

N/A

Not Applicable.

2

OVR

Overrun Error. Assertion of this bit indicates the SRT received a data word with a Transmit

Command.

1-0

N/A

Not Applicable.

2.3.3 Mode Code Data

The transmit and receive data structures for mode codes are similar to those for subaddress. The receive data structure contains an

Information word, Time-Tag word, and message data word. All receive mode codes with data have one associated data word. Data

storage occurs at the memory location pointed to by the data pointer plus two locations. Reception of the synchronize with data

mode code automatically loads the Time-Tag counter and stores the data word at the address defined by the data pointer plus two

locations.

The transmit mode code data structure contains an Information word, Time-Tag word, and associated data word. The subsystem or

host is responsible for linking the SRT Data Pointer to the data (e.g., Transmit Vector word). For mode codes with internally generated

data words (e.g., Transmit BIT word, Transmit Last Command), the transmitted data word is added to the data structure.

For MIL-STD-1553A mode of operation, all mode codes are defined without data words. For mode codes without data, the data

structure contains the Message Information word and Time-Tag word only.

Note: In MIL-STD-1553A, all mode codes are without data and the T/R bit is ignored. See section 2.9 for the MIL-STD-1553A

operation.
