MIL-STD-1553 interface device having concurrent remote terminal and monitor terminal operation
First Claim
1. An integrated circuit, for interfacing with a MIL-STD-1553 serial, asynchronous, digital time-division multiplexed communications data bus, the integrated circuit comprising:
- means for operating in the MIL-STD-1553 remote terminal mode of operation, including means for processing informational messages in the MIL-STD-1553 message format for transmission and reception on the MIL-STD-1553 bus; and
means for operating in the MIL-STD-1553 monitor terminal mode of operation concurrently with said remote terminal mode of operation, including means for monitoring selected MIL-STD-1553 messages transmitted on the MIL-STD-1553 bus.

Abstract
An integrated circuit ("IC") implementing the three MIL-STD-1553 defined functions of bus controller, remote terminal, and monitor terminal has a register based architecture that allows for concurrent remote terminal and monitor terminal operation. The IC may communicate on the bus in the remote terminal mode of operation for only one specific address. For a plurality of other addresses, the IC may monitor the bus in the monitor terminal mode of operation. While concurrently configured, the IC is precluded from monitoring its own remote terminal address, and the remote terminal has priority over the monitor terminal for message processing.
