Description
BUSACK Bus acknowledge output. LOW during DMA Handshake, in response to BUSGRNT.
DB1
Bit 1 of 16 bit parallel bus.
DB3
DB5
Bit 3 of 16 bit parallel bus.
Bit 5 of 16 bit parallel bus.
DB7
Bit 7 of 16 bit parallel bus.
DB9
DB11
Bit 9 of 16 bit parallel bus.
Bit 11 of 16 bit parallel bus.
DB13
Bit 13 of 16 bit parallel bus.
DB15
STATERR
Bit 15 of 16 bit parallel bus.
BC output indicates one or more bits set or address mismatch in a received status
word.
TXDATA A Bipolar serial data output to negative input of bus transceiver.
RXDATA A
NODT
RTAD0
Bipolar serial data input from positive output of bus transceiver.
No data input. Logic "0" indicates the 1553 bus is idle; HIGH means device front end is
active.
LSB of 5 bit RT address.
RTAD2 Bit 2 of RT address.
RTAD4
BCSTRCV
Bit 4 of RT address.
Broadcast receive. Logic "0" means the current command was a broadcast command.
TXDATA B Bipolar serial output to positive input of bus transceiver.
RXDATA B
SOM
Bipolar serial input from negative output of bus transceiver.
Start of message output indicates beginning of RT/BC message transfer sequence.
