A single write cycle is used to transfer a word to the HI-1575, which encodes the data, adds the selected Sync and Parity bits, and transmits the word on the chosen MIL-STD-1553 data bus. Complete MIL-STD-1553 messages may be transmitted by executing multiple write cycles to the device.
Activity on both MIL-STD-1553 data buses is continuously monitored. When the HI-1575 detects a properly encoded word, a hardware interrupt is generated and the information is decoded and stored in one of two internal registers, which may then be read by the host processor. Bits in the internal Status & Mode Register indicate on which bus the word was received and whether the word had a Data or Command Sync.
