DESCRIPTION
The HI-1575 is a low power CMOS dual transceiver with
on-chip Manchester II Encoder and dual Decoder
designed to meet the requirements of the MIL-STD-1553
specification. The part acts as a "Smart Transceiver",
allowing users to transmit and receive properly encoded
MIL-STD-1553 Command and Data words between a
16-bit host processor and dual MIL-STD-1553 data
buses.
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.
